Übersicht
Description
Key features:
- 16-bit resolution with no missing codes
- ±0.5 LSB INL, ±0.5 LSB DNL (max) for high accuracy
- SPI-compatible serial interface (up to 50 MHz)
- Internal reference (4.096V) with low drift (15 ppm/°C)
- Small 10-pin VSSOP (DGS) package
Ideal for portable medical devices, industrial sensors, and data acquisition systems requiring high-speed, low-power ADC performance.

Pinout
Pin Functions:
1. VDD: Power supply (2.7V–5.25V).
2. GND: Ground.
3. VREF: Reference input (2.5V max).
4. IN+: Positive analog input.
5. IN-: Negative analog input (often tied to GND for single-ended use).
6. CS: Chip select (active low).
7. SCLK: Serial clock input.
8. SDI: Serial data input (for daisy-chaining).
9. SDO: Serial data output.
10. BUSY: Conversion status output.
Key Features:
- SPI-compatible interface.
- Low power: 3.5mW at 5V, 1MSPS.
- Single-ended or differential input.
Compact and efficient for precision data acquisition.
Application
- Medical Devices: Patient monitoring, portable diagnostics.
- Industrial Automation: Process control, data acquisition.
- Test & Measurement: Oscilloscopes, spectrum analyzers.
- Energy Monitoring: Smart meters, power quality analysis.
- Automotive: Sensor interfaces, battery management.
Its small size (VSSOP-10) and low power (2.5 mW at 1 MSPS) make it ideal for space-constrained, battery-powered systems.
