Product Overview
The OPA2202 is a Texas Instruments dual precision operational amplifier in the Signal_Chain category. It integrates two amplifier channels and is specified with low input offset voltage, low drift, low input bias current, and low voltage noise density for precision analog signal paths.
Recommended operation covers 4.5 V to 36 V single-supply rails or ±2.25 V to ±18 V dual-supply rails, with a specified temperature range from -40°C to +105°C. The recommended common-mode input range is (V-) + 1.5 V to (V+) - 1.5 V, with common-mode rejection specified at 114 dB minimum and 131 dB typical across that range.
Package options include 8-pin VSSOP (DGK) measuring 3.00 mm x 3.00 mm and 8-pin SOIC (D) measuring 4.90 mm x 3.91 mm. Thermal information lists junction-to-ambient resistance of 180.1°C/W for VSSOP and 121.5°C/W for SOIC. The device also specifies heavy capacitive load drive of 25 nF with 5 µs settling time, supporting amplifier stages that must drive larger capacitive loads.
