Description
- Channels: 8 differential/15 pseudo-differential inputs.
- Resolution: 24-bit with low noise (22.5nV/√Hz).
- Flexibility: Programmable gain (1–128), output data rates (1.17–19.2kSPS), and power modes.
- Integrated Features: On-chip PGA, reference, and diagnostics (sensor burnout detection, CRC).
- Interfaces: SPI-compatible serial interface.
- Power Supply: 2.7–5.25V, with ultra-low current consumption (50µA in standby).
Ideal for industrial, medical, and instrumentation systems requiring high accuracy (e.g., RTDs, thermocouples, strain gauges). Its small 32-lead LFCSP package suits space-constrained designs.
For detailed specs, refer to the [datasheet](https://www.analog.com/media/en/technical-documentation/data-sheets/AD7124-8.pdf).
Equivalent
- ADS124S08 (TI) - 24-bit, 8-channel, low-power ADC.
- LTC2498 (Analog Devices) - 24-bit, 8/16-channel ADC with high accuracy.
- MAX11270 (Maxim Integrated) - 24-bit, 8-channel, low-noise ADC.
- MCP3551 (Microchip) - 22-bit, single-channel (lower resolution but cost-effective).
These alternatives offer similar precision and features for sensor measurement applications.
