SLAS382 is a single-channel codec with noise-shaped Delta Sigma ADC and DAC technology, low supply voltage and current: – 1.3 V typical power supply – 350 µA typical supply current drain – Power supply up monitor and low battery monitor that also automatically shuts off H-bridge output when battery decays below 1.05 V in a nontransient manner.
The Texas Instruments AIC111 is a 1.3 V microPower™ DSP/uC voice‑band audio codec that combines a noise‑shaped delta‑sigma ADC and DAC, a programmable gain amplifier/compressor, and an H‑bridge speaker driver. It targets hearing instruments, personal medical devices, low‑power headsets and other audio processing applications.
The device is offered in a 32‑pin QFN 5 × 5 mm plastic package and in a 32‑pad bumped‑die wafer‑scale (waffle) or tape‑and‑reel form. It provides a typical 108‑dB dynamic range, 0.01 % THD, 55‑dB PSRR and a low‑jitter 5 MHz clock output. Electrical limits, pin assignments and functional block diagrams are detailed throughout the specification.
