14bits 8KHz Sigma-Delta ADC

adc0420x

GENERAL DESCRIPTION

FEATURES

This adc0420x is developed for AFE (Analog-front-end)

function for voice signal processing with 14bit 8kHz

A/D conversion. The core consists of serial interface

and band-pass filters utilizing the sigma-delta A/D

conversion architecture. Also it has AAF (anti-aliasing

filter) and pre-amplifier for signal gain with external

resistor configuration. On-chip voltage reference

provide the single supply operation in analog blocks.

And it has analog 3.3volts supply operation and digital

1.8volts supply operation.

- Analog 3.3Volt / Digital 1.8Volt Operation

- Linear 14bits Output

- 8bits u/A-Law Companding Outputs

- Serial Data Output Format

- On Chip Band Pass Filter

- High Pass Filter On-Off

- On Chip Preamp for External Resister Signal Gain

APPLICATIONS

- Voice Signal Recording
