SIGNAL PROCESSING TECHNOLOGIES INTRODUCES ENHANCED 8-BIT, 250 MSPS A/D CONVERTER


SPT7722 delivers higher performance at lower price and power dissipation

COLORADO SPRINGS, Colorado -- February 4, 2002 -- Signal Processing Technologies, Inc. announces the SPT7722, the best performing 8-bit 250 MSPS analog-to-digital converter (ADC) on the market today.

With the SPT7722, SPT adds another new part to its 8-bit 200-250 MSPS family of ADCs. The SPT7722 delivers both improved linearity and dynamic performance at the same speed and resolution as its predecessor, the SPT7721. An additional member of this family is the SPT7720, an 8-bit 200 MSPS ADC.

"The SPT7722 is an excellent choice in applications requiring a high sample rate and superior performance," says Olav Lindquist, SPT's marketing manager. A DLE of ±0.4 LSB and ILE of ±0.9 LSB (typ), combined with a high input bandwidth of 350 MHz, make the part ideal for applications that require digitization of pre-sampled waveforms and very accurate presentation of these waveforms (for example, digital instrumentation such as
oscilloscopes). Another important requirement of these applications is the capability to shut down the converter
when not in use to save on overall system power. The SPT7722 has a built-in sleep mode feature with typical power dissipation of only 13.5 mW.

The SPT7722's low power dissipation of 450 mW and its low price (both 30% less than the nearest competitor) make this device particularly well-suited for cost- and power-sensitive communications applications such as wireless local loops and wireless network applications.

Another key application is RGB video displays, where the SPT7722's high sample rate allows designers to create
flat panel displays with higher resolution than ever before. Portable solid-state projectors can also benefit from the
high sample rate with a higher-resolution projection element.

Pricing and Availability

The SPT7722 is available in a 44-lead TQFP surface mount package over the industrial temperature range of -40 to +85 degrees C. Samples and production quantities are now available. The product sells for $24.20 each in quantities of 1,000.
