40V Precision Instrumentation Amplifier with
Differential ADC Driver
ISL28617
The ISL28617 is a high performance, differential input, differential
output instrumentation amplifier designed for precision
analog-to-digital applications. It can operate over a supply range of 8V
(±4V) to 40V (±20V) and features a differential input voltage range
up to ±34V. The output stage has rail-to-rail output drive capability
optimized for differential ADC driver applications. Its versatility and
small package makes it suitable for a variety of general purpose
applications. Additional features not found in other instrumentation
amplifiers enable high levels of DC precision and excellent AC
performance.
The gain of the ISL28617 can be programmed from 0.1 to
10,000 via two external resistors, RIN and RFB. The gain accuracy
is determined by the matching of RIN and RFB. The gain resistors
have Kelvin sensing, which removes gain error due to PC trace
resistance. The input and output stages have individual power
supply pins, which enable input signals riding on a high common
mode voltage to be level shifted to a low voltage device, such as
an A/D converter. The rail-to-rail output stage can be powered
from the same supplies as the ADC, which preserves the ADC
maximum input dynamic range and eliminates ADC input
overdrive.
The ISL28617 is offered in the 24 Ld TSSOP package, and is
guaranteed over -40°C to +125°C operation.
