Quad 12-bit/10-bit/8-bit DACs include 10ppm/°C reference

Milpitas, Calif.—Linear Technology Corp. has introduced the LTC2634 quad 12-bit, 10-bit and 8-bit rail-to-rail digital-to-analog converters (DACs), which integrate a precision reference in tiny 3mm x 3mm QFN and MSOP packages for industrial, automotive and ATE applications.

By integrating a 10ppm/°C reference, the LTC2636 offers further space reduction for compact circuit boards. The LTC2634 offers 12-bit performance of ±2.5LSB (max) INL error and < 2.4nVs crosstalk, ensuring that a voltage change on one DAC has minimal effect on the other DACs. Operating from a single 2.7V to 5.5V supply, supply current is a low 125µA per DAC.

The LTC2634 DACs are available in a number of ordering options to meet a wide range of applications. In addition to selecting one of three resolution options, designers can also choose between a 2.5V or 4.096V full-scale range. Ordering options provide the choice between powering up the DACs at zero-scale or mid-scale, offering flexibility for designs that cannot be forced to ground when power is first applied. Designers can choose between an MSOP-10 package or a 16-pin 3mm x 3mm QFN package that includes a hardware load-DAC (LDAC) pin, a clear pin that asynchronously forces the DAC outputs to their respective reset state, and a serial data output pin.

All LTC2634 options are guaranteed over three temperature ranges: automotive (-40°C to +125°C), industrial (-40°C to +85°C), and commercial (0°C to +70°C).

Pricing: Begins at $2.03 each for the 8-bit options, in 1,000-piece quantities.
Availability: Now.
