ADS8509

SLAS324A–OCTOBER 2004–REVISED JUNE 2005

16-BIT 250-KSPS SERIAL CMOS SAMPLING ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

•

250-kHz Sampling Rate

The ADS8509 is

complete 16-bit sampling

analog-to-digital (A/D) converter using state-of-the-art

CMOS structures. It contains a complete 16-bit,

capacitor-based, successive approximation register

(SAR) A/D converter with sample-and-hold, refer-

ence, clock, and a serial data interface. Data can be

output using the internal clock or can be

synchronized to an external data clock. The ADS8509

also provides an output synchronization pulse for

ease of use with standard DSP processors.

•

4-V, 5-V, 10 V, ±3.33-V, ±5-V, and ±10-V Input

Ranges

•

±2.0 LSB Max INL

±1 LSB Max DNL, 16-Bit No Missing Codes

SPI Compatible Serial Output with

Daisy-Chain (TAG) Feature

•

Single 5-V Supply

Pin-Compatible With ADS7809 (Low Speed)

and 12-Bit ADS8508/7808

The ADS8509 is specified at a 250-kHz sampling rate

over the full temperature range. Precision resistors

provide various input ranges including ±10 V and 0 V

to 5 V, while the innovative design allows operation

from a single +5-V supply with power dissipation

under 100 mW.

•

Uses Internal or External Reference

70-mW Typ Power Dissipation at 250 KSPS

20-Pin SO and 28-Pin SSOP Packages

Simple DSP Interface

The ADS8509 is available in 20-pin SO and 28-pin

SSOP packages, both fully specified for operation

over the industrial -40°C to 85°C temperature range.
