This device is used for the analog signal input stage for the 18-bit, stereo audio, sigma-delta, analog-to-digital AVAILABLE OPTIONS PACKAGE TA SMALL OUTLINE (NS) converter (ADC) TLC320AD58C exclusively. The 0°C to 70°C TL32088CNS TL32088 can convert input signals from single-ended to differential and differential to single-ended. The TL32088 also implements a single-ended to single-ended and differential to differential amplifier buffer. The differential output can be connected to the TLC320AD58C directly. The TLC32088 is composed of high performance amplifiers that offer wide output swing with low distortion and low noise. The reference voltage for the internal amplifier circuit is provided from a...
