AD1779

The AD1779 is a complete,14-bit monolithic analog-to-digital converter consisting of a sample-hold amplifier (SHA),a microprocessor compatible bus interface,a voltage reference and clock generation circuitry.The 14 data bits are accessed by a 16-bit bus in a sigle read operation.Data format is straight binary for unipolar mode and twos complement binary for bipolar mode.The input has a fullscale range of 10 V with a full power bandwidth of 1 MHz and a full linear bandwith of 500 kHz.High input impedance (10 M) allows direct connection to unbuffered sources without signal degradation.

This product AD1779 is fabricated on analog devices'BiMOS process,combining low power CMOS logic with high precision,low noise bipolar circuits;laser-trimmed thin-film resistors provide high accuracy.The converter utilizes a recursive subranging algorithm,which includes error correction and flash converter circuitry to achieve high speed and resolution.

The AD1779 operates from +5V and ±12V supplies and dissipates 720 mW.A 28-pin plastic DIP and 0.6 wide ceramic DIP are avaiable.Contact factory for surface-mount package options.
