Linear Technology’s LTC2654 is a 16-bit digital-to-analogue converter with quad output voltage
16-bit Quad Voltage DAC
Linear Technology Corporation introduces the LTC2654, a quad voltage output 16- and 12-bit digital-to-analogue 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 multi-channel, 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/C typical and 10ppm/C 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 8.9s settling time for a half-scale step and 3nVs 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.

The LTC2654 offers a wide range of options to meet application specific requirements. Designers can choose between 16- or 12-bit resolution and an internal 1.25V or 2.048V reference, which produce a full-scale output voltage of 2.5V or 4.096V. Alternatively, an external reference up to half the supply voltage can be used for rail-to-rail operation. The LTC2654 includes a hardware option to power up the DAC outputs at zero-scale or mid-scale, allowing more flexibility for designs that cannot be forced to ground when power is first applied. LTC2654 16-bit and 12-bit DACs and demo boards are now available. Pricing begins at $4.80 each for the 12-bit options and $11.70 each for the 16-bit options in 1,000-piece quantities.
