AD4130-4BCPZ - 24-Bit Ultra-Low Power Sigma-Delta ADC | Analog Devices
MPN: AD4130-4BCPZ ✓ NakahandaAD4130-4BCPZ Ulas
An ADC (analog-to-digital converter) is a device that converts continuous analog signals into discrete digital numbers. The AD4130-4 is a sigma-delta ADC, which uses oversampling and noise shaping to achieve high resolution (24 bits) and excellent noise performance for low-bandwidth signals. It belongs to the family of precision data converters, which are essential in industrial process control, medical instrumentation, and smart sensor nodes. The integration of a PGA and multiplexer reduces external component count and simplifies system design.
Key features include 4 differential or 8 single-ended/pseudo-differential inputs, a crosspoint multiplexer that allows any input pair to be routed to the PGA and ADC, and built-in diagnostic functions such as open-wire detection, internal temperature sensor, reference detection, and analog input overvoltage/undervoltage detection. The device also supports duty cycling modes (1/4 or 1/16) to reduce average current to as low as 5 μA, and a standby mode at 0.5 μA and power-down mode at 0.1 μA.
The AD4130-4 uses a 24-bit sigma-delta modulator with a digital filter, providing high accuracy and noise rejection. The smart sequencer and per-channel configuration minimize host processor load, while the deep 256-sample FIFO allows autonomous data collection. The SPI interface enables easy integration with microcontrollers. The device is specified for operation from -40°C to +125°C, suitable for industrial environments.
Typical applications include industrial process control (4-20 mA loops), temperature and pressure measurement, battery monitoring, and portable medical devices. Its ultra-low power consumption and integrated diagnostics make it particularly suited for smart transmitters and IoT sensor nodes.
When designing with the AD4130-4, ensure proper decoupling of the analog supply and reference pins, and use a clean ground plane to minimize noise. The SPI interface should be isolated if used in noisy industrial environments.

Talaan ng Disenyo
The AD4130-4BCPZ operates from a single analog supply of 1.71 V to 3.6 V. Use a low-noise LDO such as the ADP150 to provide a clean supply. Decouple AVDD and DVDD with 0.1 μF and 10 μF capacitors placed close to the pins. The reference inputs should be decoupled with 0.1 μF and 1 μF capacitors to ensure stable operation.
For optimal performance, use a solid ground plane and separate analog and digital ground planes if necessary. Place the ADC close to the sensor to minimize trace length. Route analog inputs away from digital signals to reduce noise coupling. Use a 4-layer PCB with dedicated power and ground planes for best results.
Avoid exceeding the absolute maximum ratings on any pin. Ensure the SPI lines are not driven above VIO. The exposed pad (EP) must be soldered to the ground plane for thermal and electrical performance. Do not leave unused inputs floating; connect them to AVSS or configure them as outputs. Use the internal temperature sensor for diagnostics if needed.
