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.
