TLC320AD50 描述
The TLC320AD50C, TLC320AD50I, and TLC320AD52C provide high-resolution signal conversion from digital-to-analog (D/A) and from analog-to-digital (A/D) using oversampling sigma-delta technology. This device consists of a pair of 16-bit synchronous serial conversion paths (one for each direction) and includes an interpolation filter before the DAC and a decimation filter after the ADC. Other overhead functions on the chip include timing (sample rate, FSD delay) and control (programmable gain amplifier, PLL, communication protocol, etc.). The sigma-delta architecture produces high resolution A/D and D/A conversion at a low system cost.
Programmable functions of this device can be selected through the serial interface.
