AD7339 is a 5V integrated high speed ADC/Quad DAC system from Analog Devices, which includes an 8-bit parallel A-to-D converter, two 8-bit parallel DACs and two 8-bit serial DACs. It also supports single 5V power supply, on-chip reference voltage and low power mode. It is packaged in 52-lead PQFP.
The AD7339 is a composite integrated circuit that combines an 8‑bit parallel A‑to‑D converter with two 8‑bit parallel DACs and two 8‑bit serial DACs. It operates from a single +5 V supply, includes an on‑chip reference, and offers power‑down mode for unused sections. The device is supplied in a 52‑lead plastic quad flat‑pack (PQFP).
Key features include a 2.048 MSPS conversion rate, 8‑bit resolution, selectable analog input range, and detailed pin configurations for both parallel and serial DACs. The datasheet provides specifications, timing diagrams, absolute maximum ratings, grounding and layout recommendations, and an ordering guide for the AD7339 and its temperature‑graded variant AD7339BS.
| Resolution (ADC) | 8 Bits |
|---|---|
| Conversion Rate | 2.048 MSPS |
| Analog Input Range | +1 V max |
| Supply Voltage (AVDD, DVDD) | 4.5 V to 5.5 V |
| Reference Voltage | 2.5 V nominal |
The AD7339 converts analog samples at a rate of 2.048 MSPS.
Both AVDD and DVDD should be between 4.5 V and 5.5 V.
The on‑chip bandgap reference provides a nominal 2.5 V output.
