Features General Description - Low Operating Current with 9m A APA2069 is a monolithic integrated circuit, which pro- - Improved Depop Circuitry to Eliminate Turn-on vides precise DC volume control, and a stereo bridged and Turn-off Transients in Outputs audio power amplifiers capable of producing 2.6W - High PSRR (2W) into 4Ω with less than 10% (1.0%) THD+N. The - 32 Steps Volume Adjustable by DC Voltage with attenuator range of the volume control in APA2069 is from 20d B (DC_Vol=0V) to -80d B (DC_Vol=3.54V) with 32 Hysteresis - 2.6W per Channel Output Power into 4Ω Load steps. The advantage of internal gain setting can be less ponents and PCB area. Both of the depop circuitry at 5V, BTL Mode and the thermal shutdown protection circuitry are inte- - Two Output Modes Allowable with BTL and SE grated in APA2069, that reduce pops and clicks noise Modes Selected by SE/BTL Pin during power up or shutdown mode operation. It also - Low Current Consumption in Shutdown Mode improves the power off pop noise and protects the chip (1µA) from being destroyed by over temperature and short cur- - Short Circuit Protection rent failure. To simplify the audio system design, APA2069 - bines a stereo bridge-tied loads (BTL) mode for Thermal Shutdown Protection and Over-Current speaker drive and a stereo single-end (SE) mode for head- Protection Circuitry phone drive into a single chip, where both modes are - The OUT+ Signal and the IN- Signal are Outphase easily switched by the SE/BTL input control pin signal. - Power Enhanced Package (DIP-16 / DIP-16A) - Lead Free and Green Devices Available (Ro HS pliant) Pin Configuration Applications - Note Book PC - LCD Monitor or TV SHUTDOWN 1 BYPASS 2 RIN- 3 GND 4 GND 5 LIN- 6 VOLUME 7 SE/BTL 8 16 ROUT15 VDD 14 ROUT+ 13 GND 12 GND 11 LOUT+ 10 VDD 9 LOUT- ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version...
