CXAR41191The CXAR41191 stereo headphone amplifier is designed for portable equipment where board space is at a premium. The CXAR41191 uses capless architecture to produce aground-referenced output from a single power supply, eliminating the need for large DC-blocking capacitors for output, saving cost, board space, and component height. Additionally, for CXAR41191B, the gain is set internally (-2V/V), further reducing component count. For CXAR41191A, the gain can be adjusted by external feedback resistors.
The CXAR41191 delivers up to 80mW per channel into a 32Ω load and has low 0.03% THD+N. A -78dB power supply rejection ratio (PSRR) at 217Hz allows this device to operate from noisy digital supplies without an additional linear regulator. Comprehensive click-and-pop circuitry suppresses audible clicks and pops on startup and shutdown.
The CXAR41191 operates from a single 2.7V to 5.1V supply, consumes only 5.8mA supply current, has short-circuit and thermal-overload protections, and is specified over the extended -40℃ to +85℃ temperature range. The CXAR41191 is available in a Green TDFN-3×3-10L package.
