7 Detailed Description

7.1 Overview

The OPA202, OPA2202, and OPA4202 (OPAx202) family of devices is a series of low-power, super-beta, bipolar

junction transistor (super-β BJT), input amplifiers that features superior drift performance and low input bias

current. The low output impedance and heavy capacitive load drive abilities allow designers to interface to

modern, fast-acquisition, precision analog-to-digital converters (ADCs) and buffer precision voltage references

and drive power supply decoupling capacitors. The OPAx202 achieve a 1-MHz gain-bandwidth product and a

0.35-V/μs slew rate, and consumes only 580 µA (typical) of quiescent current, making the devices a great choice

for low-power applications. These devices operate on a single 4.5-V to 36-V supply, or dual ±2.25-V to ±18-V

supplies.

All versions are fully specified from –40°C to +105°C for use in the most challenging environments. The single-

channel OPA202 is available in 8-pin SOIC, 8-pin VSSOP, and 5-pin SOT-23 packages. The dual-channel

OPA2202 is available in an 8-pin VSSOP package. The quad-channel OPA4202 is available in a 14-pin SOIC

package.
