Focusing on chip design to improve performance, Texas Instruments put its HPA07 process technology to work in the ADS1610 delta-sigma analogtodigital converter (ADC), which provides 16-bit resolution at 10 Msamples/s. This discretetime device operates from a 5-V analog and a 3-V digital supply. It also achieves an 86-dBFS signal-to-noise ratio (SNR) in a 5-MHz signal bandwidth with a 95-dB spurious-free dynamic range (SFDR) and a –94-dB total harmonic distortion (THD) (see the figure).

Jim Todsen, TI's product line manager for oversampling data converters, says that group delay is on the order of 3 ms, compared to 12 ms for the next fastest delta-sigma product on the market. With its conversion rate, low distortion, and latency, the ADS1610 fits dataacquisition, scientificinstrument, test and measurement, and communications applications.

Its internal filter has a brick wall response with a very flat passband (±0.0002 dB of ripple) followed immediately by a very wide stopband (5 to 55 MHz). Output data is supplied over a parallel interface that was designed to accommodate TMS320 DSPs. Power dissipation can be adjusted with an external resistor, allowing for reduction at lower operating speeds.

Housed in a TQFP-64 package, the ADS1610 costs $29.95 in 1000-piece quantities.
