Tổng quan

Equivalent

The AD7801BRZ is a precision voltage reference. Equivalent alternatives include:
- LT6654 (Analog Devices)
- REF5025 (Texas Instruments)
- MAX6126 (Maxim Integrated)
- LM4040 (Texas Instruments, less precise)
These offer similar performance (e.g., low noise, high accuracy) but check specs like voltage output (2.5V for AD7801BRZ), tolerance, and package compatibility for your design.

Features

The AD7801BRZ is a precision, low-power voltage reference IC with the following key features:
- Output Voltage: 2.5V (fixed)
- High Accuracy: ±0.04% (max) initial error
- Low Temperature Drift: 3 ppm/°C (max)
- Low Noise: 4 μV p-p (0.1 Hz to 10 Hz)
- Low Supply Current: 500 μA (max)
- Wide Supply Range: 4V to 36V
- Load Regulation: 5 ppm/mA (typ)
- Stable with Capacitive Loads: Up to 10 μF
- Operating Temp Range: -40°C to +125°C
- Package: 8-lead SOIC (BRZ)
Ideal for precision ADC/DAC applications, data acquisition systems, and industrial instrumentation.

Pinout

The AD7801BRZ is a 16-pin (SOIC) digital-to-analog converter (DAC) with the following key functions:
- Resolution: 8-bit
- Output Type: Voltage output (buffered)
- Interface: Parallel (8-bit data input)
- Supply Voltage: Single +5V operation
- Features: Fast settling time (100ns), low power consumption, and internal reference.
Pins include:
- Data inputs (D0–D7): 8-bit parallel data
- VOUT: Analog output
- VREF: Reference voltage input/output
- Control pins (CS, WR, LDAC): For latching and updating the DAC output.
Concise and functional for quick reference.
