The INA851 is the industrys first
high-precision instrumentation amplifier with fully differential outputs. This
device is optimized to drive inputs of modern high performance analog-to-digital
converters (ADCs) with fully differential inputs. The INA851 operates over a
very-wide, single-supply or dual-supply range. The output stage gain can be set to
either 0.2 or to 1 by shorting or floating two pins. A single external resistor sets
any input stage gain from 1 to 10,000.
Compared to other amplifiers in the
same class, the INA851 offers very-low input bias current and low input-referred
current noise as a result of super-beta input transistors. A state-of-the-art
manufacturing process provides exceptionally low voltage noise, input offset
voltage, and offset voltage drift. Additional circuitry protects the device inputs
against overvoltage up to ±40 V beyond the power-supply voltages.The device outputs
feature built-in clamping circuitry to protect the ADC or downstream device against
overdrive damage.
The device is designed for operation from either an 8-V minimum
single or ±4-V dual supply, and a maximum of 36-V single or ±18 V dual supply.
