Bipolære DACs med ekstrem lav drift
Texas Instruments lancerer nu high-voltage, bipolær DAC-familie med ektremt lave driftværdier (in english).
Texas Instruments Incorporated has introduced a four-channel, high-voltage, bipolar digital-to-analog converter (DAC).
Developed on TI’s HPA07 analog CMOS process technology, the 16-bit DAC8734 is part of a new family of high-performance, bipolar DACs, including pin-compatible 12- and 14-bit family members featuring up to six times lower drift than competing devices along with the widest operating temperature range and the highest initial accuracy.
The DAC8734 offers automated test equipment (ATE) and medical equipment designers space savings and flexibility in a 6 mm x 6 mm QFN-40 or 7 mm x 7 mm TQFP-48 package. The device is capable of driving ±16 V or 0 to +20 V across four channels, eliminating the external operational amplifier typically required for additional voltage gain. Designers need to add only a single voltage reference, such as the REF5050, for bipolar operation.
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.
