Description
The AD7982BRMZRL7 is a 16-bit, 1 MSPS, successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates from a single 2.5V to 5.5V supply, consuming low power (3.5 mW at 1 MSPS, 1.25 µW in shutdown). Key features include:
- High accuracy: ±0.6 LSB INL, ±0.5 LSB DNL.
- Flexible interface: SPI-compatible serial output.
- Low noise: 91.5 dB SNR at 1 kHz input.
- Small package: 10-lead MSOP (3x3 mm).
The ADC includes a low-drift reference buffer and supports both pseudo-differential and single-ended inputs. It’s ideal for portable instrumentation, industrial control, and data acquisition where precision and low power are critical. The "RL7" suffix indicates tape-and-reel packaging for automated assembly.
