TPA3244 Evaluation Module
1 Hardware Overview
The TPA3244EVM PurePath™ Ultra-HD evaluation module demonstrates the TPA3244DDW integrated
circuit from Texas Instruments. The TPA3244DDW is a high-performance, high-power, class-D amplifier
that enables true premium sound quality with high-efficiency class-D technology. It features an advance
integrated feedback design and high-speed gate driver error correction (PurePath Ultra-HD), which
enables ultra-low distortion across the audio band and superior audio quality. This EVM supports two BTL
(stereo 2.0) output channels, one PBTL (mono 0.1) output channel, one BTL plus two SE (2.1) output
channels, and four SE (4.0) output channel configurations. The NE5532 is a high-performance audio op
amp designed to allow TPA3244DDW operation with differential or single-ended input signals to the EVM
with differential inputs yielding the optimal performance. The TPA3244EVM is a complete 2-VRMS analog
input 2 × 40-W continuous/2 × 100-W peak stereo high-power amplifier ready for evaluation and excellent
listening experience.

1.2 TPA3244EVM Frequency Adjust
The TPA3244EVM offers hardware trimmed oscillator frequency by external control of the FREQ_ADJ pin.
The Frequency adjust can be used to reduce interference problems while using a radio receiver tuned
within the AM band, the switching frequency can be changed from nominal to lower values. These values
should be chosen such that the nominal and the lower value switching frequencies together results in the
fewest cases of interference throughout the AM band. The oscillator frequency can be selected by the
value of the FREQ_ADJ resistor connected to GND in master mode according to Table 1.
Table 1. Frequency Adjust Master Mode Selection
Master Mode Resistor to GND PWM Frequency
Nominal 10 kΩ600 kHz
AM1 20 kΩ500 kHz
AM2 30 kΩ450 kHz
For slave-mode operation, turn off the oscillator by pulling the FREQ_ADJ pin to DVDD. This configures
the OSC_I/O pins as inputs to be slaved from an external differential clock. In a master/slave system inter-
channel delay is automatically set up between the switching phases of the audio channels, which can be
illustrated by no idle channels switching at the same time. This will not influence the audio output, but only
the switch timing to minimize noise coupling between audio channels through the power supply. This will
optimize audio performance and result in better operating conditions for the power supply. The inter-
channel delay will be set up for a slave device depending on the polarity of the OSC_I/O connection such
that slave mode 1 is selected by connecting the OSC_I/O of the master device with the OSC_I/O of the
slave device with the same polarity (+ to + and – to –), while slave mode 2 is selected by connecting the
OSC_I/O's with the inverse polarity (+ to – and – to +).
1.3 TPA3244EVM Single-Ended and Differential Input
The TPA3244EVM supports both differential and single-ended inputs. For single-ended inputs, J4 or J19
jumpers are set to the SE position, so that the TPA3244EVM uses the NE5532 to convert the single-
ended input signal to differential to properly drive the differential inputs of the TPA3244. The input RCA
jack, J3, is used to provide INA inputs and RCA jack J14 is used to provide INB inputs. RCA jack J18 is
used to provide INC inputs and RCA jack J15 is used to provide IND inputs with differential inputs.
For differential input operation, J4 or J19 jumpers are set to the DIFF position, and the TPA3244EVM uses
the NE5532 to buffer the differential input signal to the differential inputs of the TPA3244. The input RCA
jack, J3, is used to provide INA, RCA jack J14 provides INB, RCA jack J18 provides INC, and RCA jack
J15 provides IND with differential inputs.
NOTE: 1. Single-ended input settings on the TPA3244EVM should only be used for channels with
output configuration BTL or PBTL, not SE. However, for best performance, a differential input
should be used when in BTL or PBTL modes.wever, for best performance, a differential inpu
2. For SE output configuration J4 or J19 jumpers for that channel must be set to the DIFF
position, so the input signal INx is mapped directly to OUTx.

1.4 TPA3244EVM Clip Overtemperature and Fault Indicators
The TPA3244EVM is equipped with LED indicators that illuminate when the FAULT or CLIP_OTW pin
goes low. See Table 2 and the TPA3244 data sheet (SLASEC6) for more details.

0 0 Overtemperature (OTE) or overload (OLP) or undervoltage (UVP). Junction temperature higher
than 125°C (overtemperature warning).
0 0 Overload (OLP) or undervoltage (UVP). Junction temperature higher than 125°C (overtemperature
warning).

1.5 TPA3244EVM LC Filter
The TPA3244EVM is equipped 10-µH inductors and 1-µF capacitors for the output LC filter. These
components are setup as a Type-2 filter shown in Figure 2, since this allows the support of both BTL and
SE output configurations required for the EVM.

NOTE: The performance of the TPA3244EVM/TPA3244 is dependent on the power supply. Design
the power supply with margins that can deliver the needed power. In low-frequency
applications, additional bulk capacitance may be needed. Replacing the bulk capacitors on
the TPA3244EVM with more capacitance may be necessary, depending on the power supply
used.

The TPA3244EVM includes component pads for optional output inductors L8 and L9. These pads fit
Coilcraft inductors UA8013-AL (7 µH) and UA8014-AL (10 µH). These dual-core inductors provide
extremely high performance in a small footprint to help shrink the solution size and cost. If using L8 and
L9, make sure to de-solder L2, L3, L4, and L5 first.
