Product details

The AD7846 is an LC using Analog Devices2MOS process fabricated 16-bit DAC with VREF+and VREF-The reference input and an on-chip output amplifier can be configured to provide unipolar output ranges (0 V to +5 V, 0 V to +10 V) or bipolar output ranges (±5 V, ±10 V).

The DAC uses a segmented architecture with 16 strings of resistors, selected by four MSBs in the DAC latch. Both contacts of each segment are buffered with an amplifier and fed into a 12-bit DAC to provide 12-bit resolution. This architecture ensures 16-bit monotonicity. The input offset voltages of the two buffer amplifiers are tightly matched, resulting in excellent integral linearity.

In addition to excellent accuracy specifications, the AD7846 offers a comprehensive microprocessor interface. It has 16 data input/output pins and control lines (CS, R/W, LDAC, and CLR). R/W and CS allow reading and writing input/output latches, which is a readback function useful for automated test equipment. LDAC allows simultaneous updates of each DAC in a multiDAC system, and the CLR line can reset the contents of the DAC latch to 00. 000 or 10 . 000, depending on the state of R/W. This means that the DAC output can be reset to 0 V in both unipolar and bipolar configurations.

The AD7846 is available in 28-lead plastic, ceramic, LCCC, and PLCC packages.
