1.1 Applications and Features
The PB1651ADC1 A/D Module is used to acquire analog signals with average
resolution and data rates (e.g. engine temperature, oil temperature). It can be
used both with the ES1651 Carrier Board (VMEbus) and with the ES4350 Car-
rier Board (VXIbus).
The PB1651ADC1 A/D Module has the following features:
• 16 differential input channels
• One A/D converter per channel with 16-bit resolution
• Accuracy ±3 mV typical, ±5 mV warranted
• Conversion rate/sampling rate 25 kSamples/s
• Input overvoltage protection ±60 V
• Input impedance > 10 MΩ
• 4th order low-pass filter 5 kHz (3 dB cutoff frequency)
