- Integrated PGA, voltage reference, and dual IDACs eliminate external components, reducing BOM cost and PCB area in portable measurement designs
- 4 analog input channels with I2C interface and 2 kSPS conversion rate enabling multi-sensor data acquisition over a two-wire bus with minimal I/O pin usage
Applications
The PADS122C04IPWR is designed for high-precision sensor signal conditioning and data acquisition in industrial instrumentation, medical devices, and process control systems requiring 24-bit resolution. Its integrated PGA allows direct connection to low-level sensors such as thermocouples, strain gauges, and bridge transducers without external amplification stages. The built-in IDACs and voltage reference also make it well suited for RTD temperature measurement, chemical sensing, and portable field instruments where low power and integration are essential.

Frequently Asked Questions
What is the resolution and sampling rate of the PADS122C04IPWR?
The PADS122C04IPWR provides 24-bit resolution with a maximum sampling rate of 2 kSPS (kilosamples per second) and a maximum conversion time of 520 µs. This combination makes it suitable for precision low-frequency measurements such as temperature, pressure, and weight sensing.
Does the PADS122C04IPWR include an on-chip voltage reference?
Yes. The PADS122C04IPWR integrates an on-chip voltage reference, eliminating the need for an external precision voltage reference component. This reduces BOM count and simplifies PCB layout for space-constrained portable and battery-powered precision measurement applications.
What interface does the PADS122C04IPWR use for communication?
The PADS122C04IPWR uses an I2C (two-wire) interface for digital communication, requiring only SDA and SCL lines. This minimizes microcontroller pin usage and allows multiple ADCs or other I2C devices to share the same bus using different device addresses.
What types of sensors can be directly connected to the PADS122C04IPWR?
The integrated programmable gain amplifier (PGA) allows direct connection of low-output sensors such as thermocouples, Wheatstone bridge strain gauges, load cells, RTDs with excitation from the on-chip IDACs, and other low-level analog transducers without requiring external signal conditioning amplifiers.
What is the analog input voltage range of the PADS122C04IPWR?
The PADS122C04IPWR accepts analog input voltages from -0.75 V to 5.05 V, accommodating a wide range of sensor output signals including those that swing slightly below ground. This range is compatible with standard 5 V single-supply and dual-supply sensor excitation configurations.
