Description

The INA849 is an ultra-low noise instrumentation

amplifier optimized for maximum accuracy in high-

resolution systems and operation over a wide single-

supply or dual-supply range. The device offers

significantly lower input bias current than competitors

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.

Precisely matched integrated resistors provide a high,

92-dB (G = 1) common-mode rejection across the full

input common-mode range. A single external resistor

sets any gain from 1 to 10,000. The current-feedback

topology of the INA849 provides wide bandwidth at

higher gains for very-small, fast-moving signals. For

example, the device provides 8 MHz of bandwidth

at G = 100, and 28 MHz at a G = 1, with a fast

0.4-µs settling time (0.01%) for directly driving high-

resolution, analog-to-digital converters (ADCs)
