INA592 High-Precision, Wide-Bandwidth e-trim™ Difference Amplifier

1 Features

3 Description

•

G = 1/2 amplifier

G = 2 amplifier

The INA592 device is a low-power, wide bandwidth

difference amplifier consisting of precision

operational amplifier (op amp) and a precision resistor

network. Excellent tracking of resistors (TCR)

maintains gain accuracy and common-mode rejection

over temperature. Unique features such as low offset

40 μV (maximum), low offset drift (2 μV/°C maximum)

high slew rate (18 V/μs), and high capacitive load

drive of up to 500 pF make the INA592 a robust, high-

performance difference amplifier for high-voltage

industrial applications. The common-mode range of

the internal op amp extends to the negative supply,

enabling the device to operate in single-supply

applications. The device operates on single (4.5 V to

36 V) or dual supplies (±2.25 V to ±18 V).

Low offset voltage: 40 μV (maximum)

Low offset voltage drift: ±2 μV/°C (maximum)

Low noise: 18 nV/√Hz at 1 kHz

Low gain error: ±0.03% (maximum)

High common-mode rejection: 88 dB (minimum)

Wide bandwidth: 2 MHz GBW

Low quiescent current: 1.1 mA per amplifier

High slew rate: 18 V/μs

High capacitive load drive capability: 500 pF

Wide supply range:

– Single supply: 4.5 V to 36 V

– Dual supply: ±2.25 V to ±18 V

Specified temperature range:

The difference amplifier is the foundation of many

commonly used circuits. The INA592 provides this

circuit function without using an expensive precision

resistor network.
