The AD7846 is a 16-bit DAC constructed with the Analog Devices, Inc., LC2MOS process. It has VREF+ and VREF− reference inputs and an on-chip output amplifier. These can be configured to give a unipolar output range (0 V to +5 V, 0 V to +10 V) or bipolar output ranges (±5 V, ±10 V). The DAC uses a segmented architecture.
The AD7846 is a 16‑bit digital‑to‑analog converter built with Analog Devices' LC‑MOS process. It offers both unipolar (0 V to +10 V) and bipolar (‑10 V to +10 V) output ranges, a segmented architecture for monotonicity, and a microprocessor‑compatible interface with read‑back, LDAC and clear functions.
The device is supplied in 28‑lead plastic, ceramic and PLCC packages, dissipates about 100 mW typical, and includes specifications for resolution, accuracy, gain/offset error, timing, and absolute maximum ratings. Pin configurations and functional block diagrams are provided for design integration.
| Resolution | 16 bits |
|---|---|
| Bipolar Output Range | -10 V to +10 V |
| Gain Error (±25 °C) | ±12 LSB (unipolar), ±6 LSB (bipolar) |
| Offset Error (±25 °C) | ±12 LSB (unipolar), ±6 LSB (bipolar) |
The AD7846 provides a 16‑bit resolution.
