16-Bit, 5MSPS

Analog-to-Digital Converter

F_DEATURES

DESCRIPTION

The ADS1605 and ADS1606 are high-speed, high-pre-

cision, delta-sigma analog-to-digital converters (ADCs)

with 16-bit resolution. The data rate is 5 mega-samples

per second (MSPS), the bandwidth (−3dB) is 2.45MHz,

and passband ripple is less than 0.0025dB (to

2.2MHz). Both devices offer the same outstanding per-

formance at these speeds with a signal-to-noise ratio up

to 88dB, total harmonic distortion down to −99dB, and

a spurious-free dynamic range up to 101dB. For even

higher-speed operation, the data rate can be doubled to

10MSPS in 2X mode. The ADS1606 includes an adjust-

able first-in first-out buffer (FIFO) for the output data.

Data Rate: 5MSPS (10MSPS in 2X Mode)

Signal-to-Noise Ratio: 88dB

Total Harmonic Distortion: −99dB

Spurious-Free Dynamic Range: 101dB

Linear Phase with 2.45MHz Bandwidth

Passband Ripple: 0.0025dB

Selectable On-Chip Reference

Directly Connects to TMS320C6000 DSPs

Easily Upgradable to 18 Bits with the

ADS1625 and ADS1626

The input signal is measured against a voltage refer-

ence that can be generated on-chip or supplied exter-

nally. The digital output data are provided over a simple

parallel interface that easily connects to digital signal

processors (DSPs). An out-of-range monitor reports

when the input range has been exceeded. The

ADS1605/6 operate from a +5V analog supply (AVDD)

and +3V digital supply (DVDD). The digital I/O supply

(IOVDD) operates from +2.7 to +5.25V, enabling the

digital interface to support a range of logic families. The

analog power dissipation is set by an external resistor

and can be reduced when operating at slower speeds.

A power down mode, activated by a digital I/O pin, shuts

down all circuitry. The ADS1605/6 are offered in a

TQFP-64 package using TI PowerPAD technology.

The ADS1605 and ADS1606, along with their 18-bit

counterparts, the ADS1625 and ADS1626, are well

suited for the demanding measurement requirements

of scientific instrumentation, automated test equip-

ment, data acquisition, and medical imaging.
