Linear Technology Corporation introduces the LTC2654, a quad voltage output 16- and 12-bit digital-to-analog converter (DAC family) with internal reference and SPI interface. LTC2654 DACs achieve 16-bit performance of ±4LSB INL maximum over temperature, a factor of two better than the nearest 16-bit quad competitor with internal reference.
LTC2654 has the lowest offset error ±2mV (max) and lowest gain error 0.1% (max), a combination that ensures that the LTC2654 remains accurate near the supply rails and provides users with a wider effective output range. LTC2654's precision specifications make it ideal for multichannel, open loop and closed loop systems. Applications include mobile communication, process control and industrial automation, automated test equipment (ATE) and automotive systems.
The LTC2654's integrated reference achieves 2ppm/ºC typical and 10ppm/ºC maximum temperature coefficient. It is offered in tiny 20-pin 4mm x 4mm QFN and 16-pin TSSOP packages, providing space savings densely packed circuit boards. AC performance stands out, as LTC2654 offers 8.9µs settling time for a half-scale step and 3nV•s crosstalk, resulting in minimal disturbance between DAC channels. The LTC2654 operates from a single 2.7V to 5.5V supply and communicates via a 4-wire SPI/Microwire compatible interface up to 50MHz.
