Audio Amp Headphone/Speaker 1-CH Mono/2-CH Stereo 1W Class-AB 10-Pin HTSSOP EP T/R, TPA0253DGQR, Texas Instruments

The TPA0253 is a 1-W mono bridge-tied-load (BTL) amplifier designed to drive speakers with as low as 😯 speaker. The gain of the input stage is set by the user-selected input resistor and a 50-kO/RI in BTL mode. The input terminals are high-impedance CMOS inputs, and can be used as summing nodes. The TPA0253 is available in the 10-pin thermally-enhanced MSOP package (DGQ) and operates over an ambient temperature range of –40°C to 85°C.

Ideal for Notebook Computers, PDAs, and Other Small Portable Audio Devices
