DESCRIPTION

The ADS8327 is a low power, 16-bit, 500-kSPS

analog-to-digital converter with a unipolar input. The

device includes a 16-bit capacitor-based SAR A/D

converter with inherent sample and hold.

•

Excellent AC Performance at f_I= 10 kHz with

91 dB SNR, 100 dB SFDR, –96 dB THD

•

Built-In Conversion Clock (CCLK)

The ADS8328 is based on the same core and

includes a 2-to-1 input MUX with programmable

option of TAG bit output. Both the ADS8327 and

ADS8328 offer a high-speed, wide voltage serial

interface and are capable of chain mode operation

when multiple converters are used.

1.65 V to 1.5×(+VA) I/O Supply

–

SPI/DSP Compatible Serial

SCLK up to 50 MHz

•

Comprehensive Power-Down Modes:

–

Deep Power-Down

Nap Power-Down

These converters are available in a 16-lead TSSOP

or 4x4 QFN packages and are fully specified for

operation over the industrial –40°C to +85°C

temperature range.

Auto Nap Power-Down
