Présentation
Description
Key highlights:
- 24-bit resolution with no latency (single-cycle conversion).
- Flexible input ranges (differential or single-ended).
- SPI-compatible serial interface for easy microcontroller integration.
- Ultralow power (0.75mA typical) with auto-shutdown.
Ideal for precision measurement in industrial, medical, and instrumentation applications. The IGN package (SSOP-16) ensures compact PCB integration.
Equivalent
1. ADS124S08 (TI) - 24-bit, low-noise ADC.
2. AD7124-4 (Analog Devices) - 24-bit, low-power ADC.
3. MAX11270 (Maxim) - 24-bit, high-precision ADC.
4. MCP3551 (Microchip) - 22-bit, low-cost alternative.
These offer similar resolution and performance for precision measurement applications. Check datasheets for exact compatibility.
Features
- 24-bit resolution with no latency (single-cycle conversion).
- Differential input with ±VREF range (up to ±2.5V).
- Programmable speed/power: 6Hz to 3.5kHz output rate.
- Ultra-low noise: 600nV RMS at 6Hz, 1.5μV RMS at 3.5kHz.
- Internal oscillator, no external clock needed.
- SPI-compatible serial interface.
- Low power: 1.5mA (typ) at 3.5kHz, 200μA at 6Hz.
- Wide supply range: 2.7V to 5.5V.
- Integrated PGA (1x to 256x gain).
- -40°C to +85°C operating range.
Ideal for high-accuracy applications like weigh scales, RTD sensors, and industrial measurements.
Pinout
