3 Description
The INA851 is the industry's 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 superbeta
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.
