The DAC8234 is a high-accuracy, quad-channel, 14-bit digital-to-analog converter (DAC) that operates from supply voltages of ±5V to ±18V in bipolar output mode, and from ±5V to +24V/-12V in unipolar mode. With a 5V reference, the DAC8234 can be configured to output ±10V, ±5V, 0V to 20V, or 0V to 10V. The DAC8234 provides 14-bit monotonicity, excellent integral nonlinearity (INL) error of ±0.5 LSB, low glitch, and low noise over the operating temperature range of -40°C to +105°C. This device is trimmed in production for very low zero and gain errors. In addition, the DAC8234 implements a user-programmable system-level calibration function to achieve ±0.031 LSB zero error and ±0.25 LSB gain error.
The DAC8234 has integrated reference buffers and output buffers. It features a standard high-speed 1.8V, 3V, or 5V serial peripheral interface (SPI) that operates at clock rates of up to 50MHz to communicate with a DSP or microprocessor. The four DAC channels and the auxiliary registers are addressed with four address bits. The device features double-buffered interface logic for simultaneous updates of all DACs. An asynchronous load input (LDAC) transfers data from the input data register to the DAC latch, and the contents of the DAC latch set the output voltage. The asynchronous RST input sets the output of all four DACs to 0V. The VMON pin is an analog monitor output that multiplexes the individual DAC outputs or the AIN pin.
The DAC8234 is pin-compatible with the DAC8734 (16-bit) and the DAC7716 (12-bit).
