What are the key features of TLV271CDRG4?

  • Rail-to-rail output swing reaches within millivolts of both supply rails, maximizing dynamic range on single 3.3V or 5V supply systems
  • Low 550µA quiescent current per channel extends battery life in IoT sensor nodes and wearable devices without sacrificing 3MHz bandwidth
  • Ultra-low 60fA input bias current minimizes offset errors in high-impedance sensor interfaces including pH electrodes and photodiodes
  • 2.7V to 6V supply range covers single-cell lithium, dual-AA, 3.3V LVCMOS, and 5V TTL power domains from one op-amp design
  • 85dB CMRR ensures rejection of supply noise and common-mode interference in precision single-supply instrumentation amplifier configurations

What is TLV271CDRG4 used for?

The TLV271CDRG4 is well suited for single-supply sensor signal conditioning in portable medical devices, IoT environmental monitors, and industrial 4mA to 20mA transmitter front-ends where the 550µA current consumption and rail-to-rail output maximize battery life and signal resolution. It is also used in active RC filter designs operating from 3.3V supplies, benefiting from the 3MHz gain-bandwidth product to place filter poles up to several hundred kilohertz. The 60fA bias current enables accurate transimpedance measurement of photodiodes and electrochemical sensors with feedback resistors in the tens of megaohms.

Frequently Asked Questions

How does the 60fA input bias current of TLV271CDRG4 compare to standard BJT op-amps in a pH sensor interface?

A pH electrode presents source impedance up to 1GΩ, so a 60fA bias current creates only 60µV of offset error across that impedance. A typical BJT op-amp drawing 50nA would generate 50mV of error on the same source, making the measurement useless. The TLV271CDRG4 ultra-low bias current thus preserves sub-millivolt accuracy for electrochemical and glass-electrode sensors without a separate buffer stage.

At what output voltage levels does the TLV271CDRG4 rail-to-rail output operate on a 3.3V single supply?

On a 3.3V supply, the output typically swings to within 50mV to 100mV of each rail, reaching approximately 3.2V at the high end and 0.05V to 0.1V at the low end under light load conditions. This nearly full 3.1V swing utilizes over 94% of the available supply headroom, significantly more than classic op-amps that leave 1V to 1.5V dead bands at each rail.

Can TLV271CDRG4 replace a TL071 in a 5V active filter design, and what differences should a designer expect?

The TLV271CDRG4 can substitute for the TL071 in a 5V single-supply active filter. It offers 3MHz gain-bandwidth versus 4MHz for the TL071, a minor difference for audio-range filters below 100kHz. The key benefit is the rail-to-rail output, which allows signal swings down to 0V on a single 5V rail, whereas the TL071 output is limited to approximately 1V above the negative rail, losing headroom in single-supply designs.

How much power does TLV271CDRG4 consume on a 3V coin cell, and how does that compare to a 1.5mA general-purpose op-amp?

At 550µA on a 3V supply, the TLV271CDRG4 consumes 1.65mW. A general-purpose op-amp drawing 1.5mA at 3V uses 4.5mW, consuming 2.7x more power. In a coin-cell application with a 200mAh CR2032 battery, the TLV271CDRG4 would run for approximately 363 hours in continuous operation compared to only 133 hours for the higher-current alternative.
