14-bit ADC captures 250 MSps

3 February 2010 Analogue, Mixed Signal, LSI

Texas Instruments has introduced the first in a new class of high-speed analog-to-digital converters (ADCs) delivering low power consumption and excellent dynamic performance across wide signal bandwidths from DC up to 550 MHz. Typical applications include defence, test and measurement, and communications.

The ADS4149 consumes as little as 275 mW per channel at 250 MSps, while offering 72,5 dB SNR at 100 MHz input frequency. Dynamic power scaling reduces power consumption to 215 mW at 160 MSps. An optional buffered analog input provides constant input impedance across time and frequency and eliminates sample-and-hold kickback, simplifying input matching for passive and active analog front ends, while reducing passband ripple.

A 1 to 6 dB programmable gain option provides the flexibility to trade off between SNR and spurious free dynamic range (SFDR) with lowered input voltage swing. The ADS4149 family includes pin-compatible 12- and 14-bit options at 160 and 250 MSps and buffered devices to enable customers to move to lower resolutions and samples rates without altering their core design.
