What are the key features of TS924AID?
- Quad rail-to-rail output configuration maximizing dynamic range on single-supply systems
- 80 dB typical common-mode rejection ratio (CMRR) for accurate differential signal amplification
- 1800 µV maximum input offset voltage enabling precision signal conditioning
- 0.1 µA maximum bias current minimizing error in high-impedance sensor interfaces
- Internal frequency compensation for stable voltage-feedback operation without external components
- 14-pin SOIC package with 4 independent op-amp channels reducing BOM count versus discrete ICs
What is TS924AID used for?
The TS924AID is designed for multi-channel sensor signal conditioning in industrial measurement systems where 4 independent rail-to-rail amplifiers in a single 14-pin package replace discrete op-amps and save PCB area. Its 80 dB CMRR and 1800 µV offset make it suitable for bridge sensor amplification in weighing scales, pressure transducers, and temperature monitoring circuits operating from a single 3.3 V or 5 V supply. Active filter designs and audio pre-amplifier stages in consumer electronics also benefit from the high output current drive capability and rail-to-rail swing enabling full-range signal reproduction.

Frequently Asked Questions
How does the TS924AID's rail-to-rail output capability benefit single-supply sensor systems?
The TS924AID's rail-to-rail output allows its output voltage to swing to within millivolts of both the positive supply and ground on a 3.3 V or 5 V single supply, effectively utilizing the full ADC input range without wasting dynamic range in dead zones near the supply rails. In a 5 V single-supply bridge sensor amplifier, this means the output can span from 0.05 V to 4.95 V, providing approximately 4.9 V of usable swing versus the 2 V to 3 V range typical of non-rail-to-rail amplifiers.
What does the 80 dB typical CMRR of the TS924AID mean for differential sensor measurements?
The 80 dB typical common-mode rejection ratio (CMRR) of the TS924AID means that a 1 V common-mode noise signal appearing simultaneously on both input pins produces only 0.1 mV of error at the output, representing a 10,000:1 rejection ratio. In industrial environments with 50 Hz or 60 Hz mains interference coupling onto long sensor cable runs, this 80 dB CMRR significantly suppresses power-line noise, enabling accurate millivolt-level differential signals from thermocouples, Wheatstone bridges, and 4-20 mA current loops to be amplified cleanly.
How many independent amplifier channels does the TS924AID provide, and what does this mean for PCB area savings?
The TS924AID integrates 4 independent operational amplifier channels in a single 14-pin SOIC package, which has a footprint of approximately 87 mm² including pads. Four equivalent single-channel op-amps in SOT-23-5 packages would each consume about 15 mm², totaling 60 mm² plus routing area — and require 4 separate decoupling capacitors. Combining all 4 channels in one package reduces decoupling component count to 1 or 2 shared bypass capacitors and consolidates 4 ICs into one, simplifying assembly and lowering BOM management complexity.
For a 4-channel active low-pass filter design, what bias current advantage does the TS924AID offer over general-purpose op-amps?
The TS924AID's maximum input bias current of 0.1 µA ensures that even with high-value 1 MΩ filter resistors, the bias-current-induced voltage error remains below 0.1 mV, which is negligible compared to the 1800 µV maximum offset. General-purpose op-amps such as the LM324 can have bias currents of 45 nA to 90 nA, but bipolar-input devices may exhibit 250 nA or higher, creating 250 mV of error with 1 MΩ source impedances. The TS924AID's low 0.1 µA maximum bias current enables higher-impedance filter topologies that reduce capacitor values and overall filter size.
