Delta-Sigma Converter Makes Tough Measurements

The ADS1610 is a 16-bit delta-sigma a/d converter with a signal-to-noise ratio (SNR) of 86 dB, total harmonic distortion (THD) of -94 dB, and a spurious-free dynamic range (SFDR) of 95 dB over a 5-MHz bandwidth. With twice the speed of previous converters, it is well suited for demanding measurements in communications, scientific instrumentation, and test and measurement applications. A 4.4-MHz passband with 0.0002 dB of ripple enables wideband signal processing. An on-chip digital filter simplifies anti-aliasing requirements compared to SAR and pipeline ADCs. Operation is from a 5V analog supply and a 3V digital supply. It is housed in a 64-pin TQFP-64 package. Evaluation modules are available. Price is $29.95 each/1,000.
