Key Features
- Ultra-low input bias current of 0.0002 µA at 25°C eliminates significant leakage errors in high-impedance sensor interfaces
- 90 dB typical CMRR with rail-to-rail input and output swing maximizes dynamic range on single 1.8 V to 5.5 V supplies
- Internally frequency-compensated architecture ensures stable unity-gain operation without external compensation components
Applications
The TLV342SIRUGR is well-suited for portable medical instrumentation, battery-powered sensor front-ends, and precision data-acquisition circuits that require low-power dual op-amp channels on a single 1.8 V to 5.5 V supply. Its rail-to-rail swing and sub-picoamp bias current make it particularly effective for interfacing high-impedance electrochemical sensors, photodiodes, and bridge transducers. Industrial process control and wearable health-monitoring devices also rely on its low noise and wide common-mode range.

Frequently Asked Questions
How low is the input bias current of the TLV342SIRUGR, and why does it matter for high-impedance sensor circuits?
The TLV342SIRUGR specifies a maximum input bias current (IIB) of 0.0002 µA (200 pA) at 25°C, dropping to just 3 pA average across temperature. For sensors with source impedances above 1 MΩ, this sub-picoamp bias prevents significant offset voltage errors and ensures measurement accuracy in photodiode transimpedance and electrochemical sensing circuits.
What supply voltage range does the TLV342SIRUGR support, and can it operate from a single-cell Li-ion battery?
The TLV342SIRUGR is designed for single-supply operation across a wide range from 1.8 V to 5.5 V. A single-cell Li-ion battery (3.0 V to 4.2 V) falls entirely within this range, enabling battery-powered wearables and portable instruments to use both op-amp channels without a separate split supply or boost converter.
What common-mode rejection ratio does the TLV342SIRUGR deliver, and how does that benefit bridge transducer readouts?
The TLV342SIRUGR achieves a typical CMRR of 90 dB with a minimum guaranteed value of 50 dB. In a Wheatstone bridge transducer readout, a 90 dB CMRR means a 1 V common-mode noise spike at the power-line frequency is attenuated to below 32 µV at the output, preserving measurement resolution for strain gauges and pressure sensors with millivolt-level differential signals.
When is the TLV342SIRUGR a better fit than a standard dual op-amp like the LM358 for a compact IoT node?
The LM358 is limited to a minimum supply of 3 V and lacks rail-to-rail output swing, clipping signals within about 1 V of each rail. The TLV342SIRUGR operates from 1.8 V and provides true rail-to-rail input and output, allowing full signal utilization on 3.3 V MCU analog rails. Its 3 pA bias current also reduces resistor-network errors by several orders of magnitude compared to the LM358's 45 nA bias.
