What is TLC272CPWG4 used for?
The TLC272CPWG4 dual CMOS op-amp is commonly used in precision sensor amplifiers, active filters, and signal conditioning circuits for industrial and consumer applications requiring very high input impedance. Its ultra-low 60 fA input bias current makes it ideal for electrochemical sensor interfaces, pH meters, and photodiode transimpedance amplifiers where source impedance is extremely high. The 8-pin TSSOP package facilitates integration into compact PCB designs for handheld instruments, IoT nodes, and data acquisition front-ends.

Frequently Asked Questions
How low is the input bias current of the TLC272CPWG4 and what sensor types benefit from this?
The TLC272CPWG4 has a maximum input bias current of 0.06 nA (60 pA) at 25°C, making it ideal for electrochemical sensors, photodiodes, and high-impedance piezoelectric transducers where even small bias currents would create significant voltage errors across megaohm source resistances.
What supply voltage range does the TLC272CPWG4 support for single-supply battery-powered designs?
The TLC272CPWG4 operates from a maximum total supply of 16 V, supporting single-supply configurations from 3 V to 16 V or split supplies of ±8 V. This flexibility allows direct use in 3.3 V, 5 V, and 12 V battery-powered systems without additional voltage rails.
What is the CMRR specification of the TLC272CPWG4 and how does it affect signal accuracy?
The TLC272CPWG4 provides a typical common-mode rejection ratio of 80 dB with a minimum of 65 dB, ensuring that common-mode noise on both inputs is attenuated by a factor of at least 1778x. This is critical in differential sensing applications such as bridge sensor amplifiers and industrial 4-20 mA signal receivers.
For a compact motor-control PCB, how does the TLC272CPWG4's TSSOP package compare to DIP alternatives?
The TLC272CPWG4 in 8-pin TSSOP occupies roughly 30 mm2 of PCB area compared to approximately 100 mm2 for an equivalent 8-pin DIP package. This 70% footprint reduction is significant in motor-control PCBs where current sensing, feedback filtering, and protection circuits compete for board space.
Can TLC272CPWG4 replace TLC272CP in existing designs, and what are the key differences?
The TLC272CPWG4 is the TSSOP surface-mount version sharing identical electrical specifications with the TLC272CP DIP variant, including the 16 V supply limit, 60 pA bias current, and 80 dB CMRR. The only difference is the package, so re-routing the PCB footprint from DIP-8 to TSSOP-8 is all that is required for a pin-compatible upgrade.
