Input Voltage Range and Gain
The input voltage in unipolar mode is 0 V to +5 V or 0 V to +10 V. The input
voltage in bipolar mode is –5 V to +5 V or –10 V to +10 V.
The input amplifier gain can be set to 0.4975 or 0.9901 for each channel using
jumpers.
5.4.3
A/D Converter
The analog/digital converter features a 12-bit resolution and a max. sampling
rate of 20 kHz. The conversion delay is 43
m
sec.
The converter applies the successive approximation method requiring four
clock cycles for each of the twelve approximation steps.
5.4.4
Control Logic
The control logic, in conjunction with the two shift registers, forms the serial
interface to the A/D converter and the associated calibration component.
It also forms the status register, thus controlling the conversion time.
5.4.5
ID Byte
The control interface also generates an ID byte for the piggyback. The ID byte
for the PB1650ADC1.1 piggyback is $F4. The ID byte can be used to detect the
equipment of the ES1650.1 Piggyback Carrier Board using a software pro-
gram.
5.4.6
Size of the Address Range
The size of the address range occupied by the PB1650ADC1.1 in your system
is 256 bytes.
The B16 jumper on the ES1650.1 Piggyback Carrier Board has to be open for
this address range size.
