Four-channel DAC operates over industry's widest temperature range for high-precision test equipment, medical, industrial and instrumentation applications
Key features and benefits of the DAC8734
-- Lowest drift over time and temperature provides high stability: -- 2 ppm over 500 hours; 3 ppm over 1000 hours -- Bipolar output: -- Zero error temperature coefficient (TC) of +/-0.5 ppm FSR/degrees C; -- Gain error TC +/-0.5 ppm FSR/degrees C -- Unipolar output: -- Zero error TC of +/-0.2 ppm FSR/degrees C; -- Gain error TC +/-0.5 ppm FSR/degrees C -- Widest operating temperature range of -40 degrees C to 105 degrees C helps ensure performance in extreme environments -- Integral non-linearity of +/-1 LSB, maximum (0.006% FSR), is achievable even at 16-bit resolution. To further boost precision, the family is trimmed during manufacturing to a maximum gain error of 4 LSB (at 16 bits). Built-in user calibration further reduces gain error down to +/-1 LSB, maximum, with a zero error of up to 1/8 LSB -- The device's programmable output range of 2x to 4x the reference voltage for bipolar operation at +/-2 V to +/-16 V maximizes design flexibility
Availability and pricing
The 16-bit DAC8734 is available today in a 6 mm x 6 mm QFN-40 or 7 mm x 7 mm TQFP-48 package. Pricing starts at $26.95 in 1,000-unit quantities. Two additional, pin-compatible devices in the family, the 14-bit DAC8234 and the 12-bit DAC7716, are priced at $19.95 and $10.95, respectively, in 1,000-unit quantities.
