What are the key features of TLC27M7IDRG4?
- Ultra-low 0.06 nA typical bias current minimizes loading errors on high-impedance sensor sources such as photodiodes and pH electrodes
- 91 dB typical CMRR at 520 kHz gain-bandwidth product ensures precise signal amplification in noisy industrial environments
- Wide supply range from 5 V to 15 V in a compact 8-pin SOIC package covers both single-supply and split-rail analog designs
What is TLC27M7IDRG4 used for?
The TLC27M7IDRG4 is suited for precision sensor interfaces including photodiode transimpedance amplifiers, pH probe front-ends, and strain gauge bridges where its 0.06 nA bias current avoids loading errors. It serves industrial process control and medical instrumentation circuits operating on 5 V to 15 V rails that require the 65 dB minimum CMRR to reject power-supply and ground noise. The device also fits data acquisition input stages where the 500 µV maximum offset and internal frequency compensation simplify closed-loop filter design.

Frequently Asked Questions
How low is the input bias current of the TLC27M7IDRG4 and why does it matter for sensor interfaces?
The TLC27M7IDRG4 has a maximum bias current of 2 nA and a typical value of just 0.06 nA at 25°C. Such low bias current is essential when the op-amp input connects to high-impedance sources like pH electrodes or photodiodes, because even 1 nA through a 1 MΩ source impedance creates a 1 mV offset error that accumulates over temperature in precision signal chains.
What supply voltage options are compatible with the TLC27M7IDRG4 in portable instrument designs?
The TLC27M7IDRG4 operates on single supplies from 5 V up to 15 V or on dual ±2.5 V to ±7.5 V rails, covering a wide range of battery-powered and bench-top instrument designs. Its 8-pin SOIC package and internal frequency compensation reduce external component count when powering the amplifier from a regulated 5 V or 12 V bus.
How does the 91 dB typical CMRR of the TLC27M7IDRG4 benefit industrial measurement systems?
A 91 dB typical common-mode rejection ratio means that 1 V of common-mode noise appearing on both inputs is attenuated to under 30 µV at the output, which is well below the 500 µV maximum input offset of the device. This is critical in industrial 4–20 mA loop receivers and differential temperature measurement circuits where ground potentials differ by hundreds of millivolts between sensor and controller boards.
Is the TLC27M7IDRG4 a drop-in replacement for the TLC27L7 in existing PCB designs?
The TLC27M7IDRG4 and TLC27L7 are pin-compatible in the 8-pin SOIC footprint and both use a voltage-feedback topology. The TLC27M7IDRG4 offers a higher 520 kHz gain-bandwidth product compared to the lower-speed TLC27L7, making it a performance upgrade without PCB redesign for amplifier stages requiring faster closed-loop bandwidth at the same 5 V to 15 V supply range.
