Texas Instruments has introduced a family of quad-channel digital-to-analog converters (DAC) with ultra-low glitch (0,15 nV-s) and an internal 2,5 V reference with 2 ppm/°C temperature drift and 0,02% initial accuracy. This multipurpose family of 16-, 14- and 12-bit devices offers excellent multichannel performance with a combination of high accuracy, low power consumption and small footprint, making them attractive options for portable and high channel count systems in industrial process control, data acquisition and instrumentation applications.
The DAC8564/65 (16-bit) provide ±0,5 LSB differential nonlinearity and ±4 LSB integral nonlinearity, which contribute to the excellent accuracy of the devices. The DAC8164/65 (14-bit) and DAC7564/65 (12-bit) offer a relative accuracy of ±1 LSB. Very low power consumption of 2,9 mW at 3 V and a power-down feature resulting in 1,3 μA at 5 V extend battery life in portable applications.
The low-glitch performance of the DAC8564 and DAC8565 solves the common DAC problem of unwanted transient voltages which cause ringing in closed-loop systems and create harmonic distortion during waveform generation. Wider bandwidth signals are supported by a fast settling time of 10 μs to ±0,003% of full-scale range.
Additional features include power-on-reset (POR) to zero output voltage or programmable POR to either zero or mid-scale. This allows support of either binary or two's complement binary output data formats. The DACs are also offered with a serial SPI interface. Each device operates over an extended temperature range of -40°C to 105°C and a wide power supply range of 2,7 V to 5,5 V.
