18-bit DAC with ±1-LSB INL and DNL is industry’s first

Enabling the design of higher-performance instrumentation, automated test equipment, data acquisition systems, and medical devices, the 18-bit LTC2757 D/A converter is claimed to be the first to offer precision dc specifications of ±1-LSB INL max and ±1-LSB DNL max. The part is accurate over a ±10-V output range, offering a full-scale settling time of 2.1 µs and low 1.4-nV•s glitch impulse.

Six unique output voltage ranges (0 to 5 V, 0 to 10, ±10, ±5, ±2.5 V, and –2.5 to 7.5 V) can be selected using software or pin strapping, eliminating the need to add precision gain stages and allowing customers to improve production logistics and adjust inventory mix on the fly. The part also offers current-mode output and voltage-controlled offset and gain-adjustment pins.

The LTC2757 uses a bidirectional parallel input/output interface that allows readback of any internal register, as well as the DAC output span setting. Available in a 48-pin LQFP package, the DAC features 2.7 to 5.5-V single supply operation. (From $25.50 ea/1,000 — available now.)
