LTC1654IGN#PBF

LTC1654IGN#PBF is a dual channel, rail-to-rail voltage output, 14bit digital-to-analogue converter (DAC). It includes output buffer amplifiers and a flexible serial interface. It has REFHI pins for each DAC that can be driven up to VCC. The output will swing from 0V to VCC in a gain of 1 configuration or VCC/2 in a gain of 1/2 configuration. It operates from a single 2.7V to 5.5V supply. It has two programmable speeds: a FAST and SLOW mode with ±1LSB settling times of 3µs or 8.5µs respectively and supply currents of 930µA and 540µA in the two modes. It also has shutdown capability, power-on reset and a clear function to 0V. Applications include digital calibration, industrial process control, automatic test equipment, offset/gain adjustment, and multiplying DAC.

• 14bit monotonic over temperature, positive supply operation range from 2.7V to 5.5V
• Buffered true rail-to-rail voltage outputs, user selectable gain
• Power-on reset and clear function, differential nonlinearity is ±1LSB max at (TA = 25°C)
• Schmitt trigger on clock input allows direct optocoupler interface
• Integral nonlinearity is ±4LSB maximum at (VCC = 2.7V to 5.5V, TA = 25°C)
• Offset error is ±6.5mV maximum at (0°C ≤ TA ≤ 70°C, VCC = 2.7V to 5.5V, TA = 25°C)
• Supply current (SLOW/FAST) is 540µA typical at (2.7V ≤ VCC ≤ 5.5V (Note 5) SLOW)
• Output noise voltage density is 170nV/√Hz typical at (10KHz, SLOW, TA = 25°C)
• Gain error is ±24LSB maximum at (VCC = 2.7V to 5.5V, TA = 25°C)
• Operating temperature range from -40°C to +85°C, 16-lead plastic SSOP package
