INTEGRATED SUCCESSIVE-APPROXIMATION ADC SIMPLIFIES MOTOR CONTROL DESIGN WHILE PROVIDING INDUSTRY’S WIDEST DYNAMIC RANGE
Featuring two on-chip SAR ADCs, programmable gain amplifier and comparators, the AD7264 interfaces with multiple sensors to replace as many as three data acquisition boards in motor control applications.

About the AD7264
Analog Devices’ AD7264 simplifies industrial motor control designs by integrating two successive-approximation (SAR) analog-to-digital converters (ADCs), a programmable gain amplifier (PGA) and four comparators on a single chip. By providing a direct interface for multiple types of sensors, the new ADC solution allows a single, standardized data acquisition board to be used in industrial motor drives, replacing as many as three separate boards previously required to perform the same system control function. This integration allows designers to develop simpler, more cost-effective motor control units.
Designed for industrial applications, the AD7264 features two high-speed, low-power SAR ADCs, each providing throughput rates up to 1 MSPS (million samples per second). The on-chip PGA accepts a true differential analog input, and supports 13 programmable-gain settings from 1 to 128. In addition, the AD7264 includes four on-chip comparators: two optimized for low power, and two optimized for short propagation delays. Operating with a 5 V power supply, the device consumes 24 mA.
Availability and Pricing
The AD7264 is sampling now and will be available in full production quantities in January 2008. The AD7264, priced at $9.06 per unit in 1,000-unit quantities, is available in 48-lead LFCSP (lead-frame chip-scale package) and 48-lead TQFP (thin quad flat package) packaging. The AD7262, a 12-bit pin-compatible solution, is priced at $7.55 per unit in 1,000-unit quantities.
