INA848IDR General Description

Thanks to its current-feedback topology, the amplifier delivers a wide bandwidth of 2.8 MHz at a fixed gain of 2000, eliminating the need for additional gain stages. The device's noise floor of 1.3 nV/√Hz ensures minimal impact on the resolution of connected ADCs, while allowing flexibility for signal filtering between gain stages

Key Features

High sensitivity: 10 mV/V
Low power consumption: 5 mA
Precise voltage regulation: 1%
Fast slew rate: 50 V/μs
Broad temperature range: –40°C to +100°C
