Product details

The AD7237A/AD7247A are enhanced versions of the industry standard AD7237/AD7247, respectively, with improvements such as operation from 12 V to 15 V supplies, faster interface times, and reference voltage following VDDhas better volatility performance and faster settling times.

The AD7237A/AD7247A are complete dual, 12-bit, voltage outputsDigital-to-analog convertersThe output amplifier and Zener reference are integrated on a CMOS monolithic to achieve full rated performance without external user adjustment.

Both devices are microprocessor-compatible and feature high-speed data latching and interface logic. The AD7247A accepts 12 bits of parallel data that is loaded into the corresponding DAC latches via the WR input and a separate Chip Select input for each DAC. The AD7237A has a double-buffered interface structure and an 8-bit wide data bus where data is loaded into the corresponding input latch in two writes. Asynchronous LDAC signals on the AD7237A update the DAC latch and analog outputs.

These devices feature REF OUT/REF IN (Reference: External/Internal), which can be obtained from either a 5 V on-chip reference or an external reference. When operating from a single supply, it can provide both 0 V to +5 V and 0 V to +10 V output ranges; When operating from dual supplies, an additional ±5 V output range is provided in addition to the above two output ranges. The output amplifier is capable of generating +10 V to ground (GND) across a 2 kΩ load.

The AD7237A/AD7247A are linearly compatible with CMOS (LC).2MOS Process Manufacturing, an advanced hybrid process technology that combines sophisticated bipolar circuitry with low-power CMOS logic. Both devices are available in two packages: a 0.3-inch-wide, 24-pin plastic-sealed dual in-line package (DIP) and a 24-pin small integrated package (SOIC).
