18-Bit DAC Achieves ±1LSB INL/DNL

The LTC2758 dual, 18-bit, current-output DAC specifies a ±1LSB INL and DNL over temperature. Settling time is 2.1 µs and it is capable of outputting six unique unipolar and bipolar output ranges up to ±10V. Output voltage ranges include two unipolar ranges (0V to 5V, 0V to 10V) and four bipolar ranges (±10V, ±5V, ±2.5V, -2.5V, to +7.5V) that can be selected using software or pin-strapping. Other features include precision resistors for each DAC for reference inversion, bipolar offset, and gain and offset adjustment. Available tin a 7mm x 7mm LQFP-48 package, pricing begins at $27.91 each/1,000. LINEAR TECHNOLOGY CORP., Milpitas, CA. (800) 454-6327.
