AD8460

110 V High Voltage, 1 A High Current,

Arbitrary Waveform Generator with Integrated 14-Bit High Speed DAC

FEATURES

GENERAL DESCRIPTION



Wide high voltage supply range: ±12 V to ±55 V

High Output Capability

The AD8460 is a “bits in, power out” high voltage, high-power, high-

speed driver optimized for large output current (up to ±1 A) and high

slew rate (up to ±1800 V/μs) at high voltage (up to ±40 V) into

capacitive loads. Combining a 14-bit high-speed DAC, a high voltage,

high output current (HV-HI) analog driver, and fault monitoring and

protection circuits, the AD8460 is ideally suited for high power

applications such as arbitrary waveform generation (AWG),

programmable power supplies, and high voltage automated test

equipment (ATE).



Output voltage range: Up to ±40 V



High output current drive: 1 A continuous



High slew rate: ≥1800 V/µs into 1000 pF load



Large signal bandwidth: 1 MHz



Extensive Programming and Diagnostics



14-bit resolution arbitrary waveform generation (AWG) mode



16 level analog pattern generation (APG) mode

A proprietary high-voltage BCDMOS process, novel high voltage

architecture, and thermally enhanced package from Analog Devices Inc.

enable this high-performance driver. A digital engine implements user-

configurable features: modes for digital input, programmable supply

current, and fault monitoring and programmable protection settings for

output current, output voltage, and junction temperature. Analog

features extend functionality: external compensation enables unlimited

capacitive load drive, programmable shutdown delay, and full-scale

adjustment. The AD8460 operates on high voltage dual supplies up to ±55

V and a single low voltage supply of 5 V.
