Description for the DAC8734

The DAC8734 is a high-accuracy, quad-channel, 16-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 DAC8734 can be configured to output ±10V, ±5V, 0V to 20V, or 0V to 10V. The DAC8734 provides 16-bit monotonicity, excellent integral nonlinearity (INL) error of ±1 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 DAC8734 implements a user-programmable system-level calibration function to achieve ±0.125 LSB zero error and ±1 LSB gain error.

The DAC8734 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 DAC8734 is pin-compatible with the DAC8234 (14-bit) and the DAC7716 (12-bit).

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
