AD7339BSZ-REEL

ADCs/DACs - Special Purpose Overview

The AD7339BSZ-REEL is a composite integrated circuit from Analog Devices Inc., featuring an 8-bit parallel ADC, two 8-bit parallel DACs, and two 8-bit serial DACs. It operates on a single +5 V supply with an onboard 2.5 V bandgap reference. The ADC supports a conversion rate of 2.048 MSPS with a signal-to-noise ratio of 42.7 dB min. Parallel DACs update at 2.304 MHz max, while serial DACs use a gated 256 kHz clock. Each section includes individual power-down control to minimize current consumption. The device is housed in a 52-lead PQFP package (S-52) and functions within a temperature range of –40 °C to +85 °C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix 'SZ-REEL' against the manufacturer's official documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the B version temperature rating (-40 °C to +85 °C) matches system requirements. Confirm pinout compatibility with existing PCB layouts due to the 52-lead PQFP form factor.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a single IC solution is needed for mixed-signal processing with high throughput. The 8-bit resolution suits applications where cost and speed are prioritized over precision. Ensure the input signal range fits within the ±1 V ADC limit or design appropriate AC coupling. Verify that the serial interface timing aligns with the host microcontroller's SCLK capabilities.
