AD7891YSZ-1

The AD7891YSZ-1 is a 12-bit, successive-approximation analog-to-digital converter (ADC) from Analog Devices. It features fast conversion speeds (up to 1.2 µs) and operates on a single +5V supply.
Key specifications:
- Resolution: 12 bits
- Sampling Rate: Up to 600 kSPS
- Input Range: ±10V (bipolar) or 0V to +10V (unipolar), selectable via pin
- Interface: Parallel output with byte-select options
- Power Consumption: Low power (60 mW typical)
The ADC includes an on-chip track-and-hold amplifier, ensuring accurate sampling of fast signals. It is designed for industrial, instrumentation, and data acquisition systems requiring high-speed, precision conversions.
Packaged in a 28-lead SOIC (YSZ), the AD7891YSZ-1 is robust and suitable for space-constrained applications. Its ease of integration and performance make it ideal for real-time signal processing.
