The pinout is the same as the TPA2010D1 except that the external gain setting – Internal Matched Input Gain and Feedback input resistors required by the TPA2010D1 are Resistors for Excellent PSRR and CMRR integrated into the fixed gain TPA203xD1 family. – Optimized PWM Output Stage Eliminates Features like –75dB PSRR and improved LC Output Filter RF-rectification immunity with a very small PCB – PSRR (–75 dB) and Wide Supply Voltage footprint (WCSP amplifier plus single decoupling (2.5 V to 5.5 V) Eliminates Need for a cap) make the TPA203xD1 family ideal for wireless Dedicated Voltage Regulator handsets. A fast start-up time of 3.2 ms with minimal pop makes the TPA203xD1 family ideal for PDA – Fully Differential Design Reduces RF applications. Rectification and Eliminates Bypass Capacitor In wireless handsets, the earpiece, speaker phone, – CMRR (–69 dB)Eliminates Two Input and melody ringer can each be driven by a TPA203xD1. The TPA203xD1 family has a low Coupling Capacitors 27- µV noise floor, A-weighted. • Thermal and Short-Circuit Protection • Pinout Very Similar to TPA2010D1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
