Analog Devices AD7237/AD7247 Datasheet
The AD7237 and AD7247 are dual 12‑bit voltage‑output digital‑to‑analog converters that integrate on‑chip voltage reference, output amplifiers, and a parallel loading structure. They support both single‑supply (+15 V) and dual‑supply (±15 V) operation and offer selectable output ranges of 0‑5 V, 0‑10 V, and ±5 V.
Both devices are available in 24‑pin DIP and SOIC packages. The document includes full pin‑function tables, timing diagrams, electrical specifications, and example microprocessor interfacing circuits for processors such as the ADSP‑2101, 8086, and 68000.

Questions answered in these manuals
What is the resolution of the AD7237/AD7247?
Both devices provide a 12‑bit resolution.
What supply voltage does the device require?
The converters can be powered from a single +15 V supply or from dual ±15 V supplies.
What supply voltage range does the AD723 support?
The AD723 operates from a single supply voltage of 2.7 V to 5.5 V.
How does the AD723 indicate that no TV is present?
The TVDET output pin goes low, signalling that no TV is detected.
What supply voltage range does the AD7237A/AD7247A support?
It operates from +12 V to +15 V for single‑supply operation and from ±12 V to ±15 V for dual‑supply operation.
