Integrated convertor eases motor
controller design
Analogue front end combines two successive-approximation ADCs, a programmable gain amplifier and four comparators on a single chip to simplify control of industrial motors.
New from Analog Devices, the AD7264 simplifies industrial motor control designs by integrating two successive-approximation (SAR) analogue-to-digital convertors (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, standardised 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

A/D convertor measures smaller signals faster
Sigma-delta ADC achieves greater than true 16bit noise-free resolution up to 2.4kHz across all input voltages from 40mV to 5V.
SAR convertor claims record speed and accuracy
A/D convertor achieves a new level of 16bit data capture performance, with best-in-class 15bit ENOB and 10Msample/s throughput.
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 1Msample/s.
The on-chip PGA accepts a true differential analogue input, and supports 13 programmable gain settings from 1 to 128.
In addition, the AD7264 includes four on-chip comparators: two optimised for low power, and two optimised for short propagation delays.
Operating with a 5V power supply, the device consumes 24mA.
The AD7264 is sampling now and will be available in full production quantities in January 2008.
The AD7264, priced at US $9.06 per unit in 1000-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 12bit pin-compatible solution, is priced at US $7.55 per unit in 1000-unit quantities.
