CS3004

Precision Dual Low-voltage Amplifier

Features & Description

Description

The CS3004 dual amplifier is designed for precision am-

plification of low-level signals. These amplifiers achieve

excellent offset stability, high open loop gain, and low

noise. The devices also exhibit excellent CMRR and

PSRR. The common mode input range includes the sup-

ply rails. The amplifiers operate with any supply voltage

from 2.7 V to 5 V (±1.35 V to ±2.50 V).

Low Offset:

– 10 µV Max.

Low Drift:

– 0.05 µV/°C Max.

Low Noise:

– 17 nV/√Hz

Open-loop Voltage Gain:

– 150 dB Typ.
