DAC8426:  Quad 8-Bit Voltage Out CMOS DAC Complete with Internal 10V Reference

The DAC-8426 is a complete quad voltage output D/A converter with internal reference. This product fits directly into any existing 7226 socket where the user currently has a 10 V external reference. The external reference is no longer necessary. The internal reference of the DAC-8426 is laser-trimmed to ±0.4% offering a 25ppm/°C temperature coefficient and 5mA of external load driving ...More

DAC8426:  Quad 8-Bit Voltage Out CMOS DAC Complete with Internal 10V Reference

Product Description

The DAC-8426 is a complete quad voltage output D/A converter with internal reference. This product fits directly into any existing 7226 socket where the user currently has a 10 V external reference. The external reference is no longer necessary. The internal reference of the DAC-8426 is laser-trimmed to ±0.4% offering a 25ppm/°C temperature coefficient and 5mA of external load driving capability.

The DAC-8426 contains four 8-bit voltage-output CMOS D/A converters on a single chip. A 10 V output bandgap reference sets the latches and interface control logic.

One of the four latches, selected by the address inputs, is loaded from the 8-bit data bus input when the write strobe is active low. All digital inputs are TTL/CMOS (5V) compatible. The on-board amplifiers can drive up to 10mA from either a single or dual supply. The on-board reference that is always connected to the internal DACs has 5mA available to drive external devices.

Its compact size, low power, and economical cost-per-channel, make the DAC-8426 attractive for applications requiring multiple D/A converters without sacrificing circuit-board space. System reliability is also increased due to reduced parts count.

Analog Devices' advanced oxide-based, silicon-gate, CMOS process allows the DAC-8426's analog and digital circuitry to be manufactured on the same chip. This, coupled with Analog Devices' highly stable thin-film R-2R resistor ladder, aids in matching and temperature tracking between DACs.
