FEATURES

DESCRIPTION

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

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 performance 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 adjustable 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 2.45 MHz 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 reference that

can be generated on-chip or supplied externally. The digital

output data is 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.
