ADS7808U

The ADS7808U is designed as one kind of complete 12-bit sampling analogto-digital using state-of-the-art CMOS structures. It can be used in a plastic 0.3" DIP and in an SOIC, both fully specified for operation over the industrial -40°C to +85°C range. Also this device contains a 12-bit capacitor-based SAR A/D with S/H, reference, clock, and a serial data interface. Data can be output using the internal clock, or can be synchronized to an external data clock.

Features of the ADS7808U are:(1)100khz sampling rate; (2)72db sinad with 45khz input; (3)±1/2 lsb inl and dnl; (4)six specified input ranges; (5)serial output; (6)single +5v supply operation; (7)pin-compatible with 16-bit ads7809; (8)uses internal or external reference; (9)100mw max power dissipation; (10)20-pin 0.3" plastic dip and soic; (11)simple dsp interface.

The absolute maximum ratings of the ADS7808U can be summarized as:(1)ground voltage differences--DGND, AGND2:±0.3V;(2)VANA:7 V;(3)VDIG to VANA: +0.3;(4)VDIG:7 V;(5)digital inputs:-0.3V to VDIG+0.3V;(6)maximum junction temperature:+165°C;(7)internal power dissipation:700mW;(8)lead temperature (soldering, 10s):+300°C.
