The SHUTDOWN pin is fully compatible – 0.5- μA Shutdown Current with 1.8-V logic GPIO, such as are used on low- • SHUTDOWN Pin has 1.8-V Compatible power cellular chipsets. Thresholds Features like 88% efficiency, –75-dB PSRR, • Capable of Driving an improved RF-rectification immunity, and small total 8- Ω Speaker (2.5 V ≤ VDD ≤ 5.5 V) and a PCB footprint make the TPA2006D1 device ideal for 4- Ω Speaker (2.5 V ≤ VDD ≤ 4.2 V) cellular handsets. A fast start-up time of 1 ms with minimal pop makes the TPA2006D1 device ideal for • Only Three External Components PDA applications. – Optimized PWM Output Stage Eliminates LC In cellular handsets, the earpiece, speaker phone, Output Filter and melody ringer can each be driven by the – Internally Generated 250-kHz Switching TPA2006D1 device. The TPA2006D1 device allows Frequency Eliminates Capacitor and Resistor independent gain while summing signals from – Improved PSRR (–75 dB) and Wide Supply separate sources, and has a low 36- μV noise floor, Voltage (2.5 V to 5.5 V) Eliminates Need for a A-weighted. Voltage Regulator The TPA2006D1 device has short-circuit and thermal – Fully Differential Design Reduces RF protection. Rectification and Eliminates Bypass Capacitor Device Information(1) – Improved CMRR Eliminates Two Input Coupling Capacitors PART NUMBER PACKAGE BODY SIZE (NOM) TPA2006D1 VSON (8) 3.00 mm ×3.00 mm • Space-Saving 3 mm x 3 mm VSON Package (DRB) (1) For all available packages, see the orderable addendum at the end of the datasheet.
