This datasheet also covers the APA2120 variant, as both devices belong to the same stereo 2-w audio power amplifier family and are provided as variant models within a single manufacturer datasheet.
General Description
APA2120/1 is a monolithic integrated circuit, which provides precise DC volume control, and a stereo bridged audio power amplifiers is capable of producing 2.7W(2.
0W) into 3Ω with less than 10% (1.0%)THD+N.
Key Features
Low Operating Current with 14mA.
Improved Depop Circuitry to Eliminate Turn-on
and Turn-off Transients in Outputs.
High PSRR.
32 Steps Volume Adjustable by DC Voltage with
Hysteresis.
2W Per Channel Output Power into 4Ω Load at
5V, BTL Mode.
Two Output Modes Allowable with BTL and SE
Modes Selected by SE/BTL Pin.
Note: The manufacturer provides a single datasheet file (APA2120_AnpecElectronicsCoropration.pdf) that lists specifications for multiple related part numbers.
