What are the key features of TLV2444AIDG4?
- Quad op-amp with 1.8 MHz gain-bandwidth product and rail-to-rail output swing, maximizing dynamic range on 3 V to 9 V single-supply systems
- Ultra-low 150 pA maximum input bias current enables high-impedance sensor interfaces with minimal signal loading error
- 70 dB minimum CMRR and 1.5 mV max input offset voltage in a 14-pin SOIC package, suitable for precision signal conditioning
What is TLV2444AIDG4 used for?
The TLV2444AIDG4 excels in battery-powered instrumentation, portable medical devices, and sensor signal conditioning circuits where four independent op-amp channels are needed from a single 3 V or 5 V supply. Its ultra-low 150 pA bias current makes it ideal for pH electrode amplifiers, photodiode transimpedance amplifiers, and high-impedance bridge sensor circuits where leakage current must not corrupt the measurement.

Frequently Asked Questions
How does the TLV2444AIDG4's 150 pA bias current advantage manifest in high-impedance sensor circuits?
With a maximum input bias current of 0.00015 µA (150 pA), a 10 MΩ source resistance introduces only 1.5 mV of additional voltage error — comparable to the 1.5 mV offset voltage specification. In photodiode transimpedance amplifiers or pH electrode buffers, where source impedances can exceed 100 MΩ, this 150 pA maximum bias current prevents significant offset drift, ensuring measurement accuracy without large DC blocking capacitors or frequent calibration.
For a 3.3 V single-supply data-acquisition front-end, what signal range can TLV2444AIDG4 handle?
Operating from a 3.3 V single supply, the TLV2444AIDG4's rail-to-rail output can swing to within approximately 30 mV of the supply rails, providing a usable output range of roughly 0.03 V to 3.27 V. Combined with its 70 dB minimum CMRR and 75 dB typical CMRR, the amplifier rejects common-mode noise from the supply and ground lines, making it suitable as an ADC driver in data-acquisition systems with 12-bit to 16-bit converters.
When does choosing TLV2444AIDG4 over a dual op-amp reduce BOM cost in quad-channel designs?
Using a single TLV2444AIDG4 quad package replaces two dual op-amp ICs, reducing the component count from 2 packages and 2 sets of decoupling capacitors to 1 package and 1 decoupling network. This saves at least 1 passive capacitor and frees 1 PCB footprint slot, lowering assembly cost by approximately 15% to 20% per board compared to a two-IC dual op-amp solution while maintaining identical per-channel performance across 1.8 MHz bandwidth.
Which supply voltage configurations are supported by TLV2444AIDG4, and how does this affect system design?
TLV2444AIDG4 operates from single supplies of 3 V, 5 V, or 9 V, as well as split supplies up to ±4.5 V. This flexibility allows the same PCB design to function in 3.3 V microcontroller systems, 5 V industrial sensor cards, and 9 V audio circuits without component changes. The 70 dB minimum CMRR maintains signal integrity across this voltage range, simplifying multi-platform designs that share a common analog front-end.
