Tổng quan
Description
- 16-bit resolution with no missing codes.
- Throughput: Up to 250 kSPS.
- Low power: Consumes 15 mW at 250 kSPS.
- Single 5V supply operation.
- Differential input with a ±VREF range (VREF up to 5V).
- Serial interface (SPI/QSPI-compatible).
- Internal reference (2.5V) with low drift.
Ideal for precision data acquisition, industrial control, and instrumentation, the AD7667ASTZ offers high accuracy, fast conversion, and low noise. Its 40-lead LQFP package ensures compact integration.
Key advantages include excellent linearity (INL ±1 LSB) and low distortion (THD: -105 dB), making it suitable for demanding applications.
For more details, refer to the datasheet on Analog Devices' website.
