SLAS462A–JUNE 2007–REVISED MARCH 2008

16-Bit, 250kSPS, Serial, CMOS, Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

•

0V to 8.192V, ±5V, and ±10V Input Ranges

•

93dB SNR with 20kHz Input

±1.5LSB Max INL

The ADS8519 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,

reference, clock, and a serial data interface. Data can

be output using the internal clock or synchronized to

an external data clock. The ADS8519 also provides

an output synchronization pulse for ease-of-use with

standard DSP processors.

±1LSB Max DNL; 16 Bits, No Missing Codes

SPI™-Compatible Serial Output with

Daisy-Chain (TAG) Feature and 3-State Bus

•

5V Analog Supply, 1.65V to 5.25V I/O Supply

Pinout Similar to 16-Bit ADS7809 (Low-Speed)

and 12-Bit ADS7808 and ADS8508

•

No External Precision Resistors Required

Uses Internal or External Reference

110mW Typ Power Dissipation at 250kSPS

28-Pin SSOP Package

The ADS8519 is specified at a 250kSPS sampling

rate over the full temperature range. Internal precision

resistors provide various input ranges including ±10V,

±5V, and 0V to 8.192V, while the innovative design

allows operation from a single 5V supply with power

dissipation under 125mW.

Simple DSP Interface

The ADS8519 is available in

package, and is fully specified for operation over the

industrial –40°C to +85°C temperature range.
