The LTC2757 18-bit digital-to-analog converter offers precision DC specifications of ±1LSB INL (max) and ±1LSB DNL (max). The LTC2757 is 18-bit accurate over a ±10V output range, offering a full-scale settling time of 2.1µs and low 1.4nV•s glitch impulse. Fast settling and low glitch reduce harmonic distortion, making it possible to produce higher frequency, lower noise output waveforms. This unique combination of DC and AC accuracy will enable the design of higher performance instrumentation, automated test equipment, data acquisition systems, and medical devices. Two unipolar ranges (0V to 5V and 0V to 10V) and four bipolar ranges (±2.5V, ±5V, ±10V and –2.5V to 7.5V), defined as multiples of the external precision reference, 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 LTC2757 uses a bidirectional parallel input/output interface that allows readback of any internal register, as well as the DAC output span setting. Voltage-controlled offset and gain adjustment pins enable users to null system offset, gain error, or reference errors. The single serial LTC2756 will be offered in a 28-pin SSOP package, while the dual LTC2758 will be offered in the same 7mm x 7mm 48-pin LQFP package as the LTC2757.
