Product details
Overview
TLV2475CPWPR from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, delivering 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage - ideal for low-voltage sensor signal conditioning in battery-powered medical and portable data acquisition systems.
For engineers reviewing the TLV2475CPWPR datasheet, TLV2475CPWPR pinout, TLV2475CPWPR application, or TLV2475CPWPR equivalent, key selection criteria include its 3V–6V single-supply operation, 350nA/channel shutdown current at 3V, TSSOP-16 package footprint, and verified rail-to-rail I/O performance across –40°C to +125°C industrial temperature range.
Technical Context
The TLV2475CPWPR implements a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), paired with a robust output stage capable of ±35mA sourcing/sinking while maintaining 180mV rail clearance under 10mA load. Its 2.8MHz gain-bandwidth supports stable unity-gain configurations with capacitive loads up to 1000pF when using recommended RNULL compensation.
Shutdown control is implemented via dedicated SHDN pins (pins 1/2 and 15/16) that place outputs in high-impedance state and reduce per-channel supply current to 350nA at 3V or 1000nA at 5V. The device operates fully specified across –40°C to +125°C with 2.7V–6V supply, meeting stringent requirements for industrial sensing and precision analog front-ends.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474CPWP | No shutdown functionality; identical pinout, GBW, and drive capability | Suitable where continuous operation is required and power cycling is unnecessary | Select when system-level power management is handled externally and cost reduction is prioritized |
| OPA4340UA | Higher 5.5MHz GBW but 750μA/channel supply current; no shutdown; SO-14 package | Better for higher-frequency signal chains but consumes 25% more active power and lacks per-pair disable | Choose when bandwidth >3MHz is mandatory and TSSOP-16 footprint is not required |
Compared with TLV2474CPWP, TLV2475CPWPR adds independent shutdown control for two amplifier pairs at minimal cost premium, while OPA4340UA trades power efficiency for bandwidth - making TLV2475CPWPR optimal for battery-constrained, multi-channel, intermittently active sensor systems.

FAQ
What is the maximum operating supply voltage for TLV2475CPWPR?
The absolute maximum supply voltage for TLV2475CPWPR is 7V, but the recommended operating range is 2.7V to 6V. Operation above 6V risks parametric shift and reduced reliability; designs must include overvoltage protection if transient spikes exceed this limit. The device is fully characterized at 3V and 5V across its full temperature range.
Does TLV2475CPWPR support true rail-to-rail output swing under load?
Yes, TLV2475CPWPR delivers rail-to-rail output swing: it drives to within 180mV of each rail at ±10mA load and maintains ±35mA sourcing/sinking capability at 500mV from the rails. This is verified across –40°C to +125°C and enables direct interfacing with 3V ADCs and reference buffers without external level-shifting circuitry.
How does the shutdown function work on TLV2475CPWPR?
TLV2475CPWPR has two independent shutdown pairs: pins 1/2 control channels 1/2, and pins 15/16 control channels 3/4. Driving any SHDN pin ≤0.8V places its associated amplifier outputs in high-impedance state and reduces per-channel supply current to 350nA (at 3V) or 1000nA (at 5V). All amplifiers remain functional when SHDN pins are ≥2V.
Can TLV2475CPWPR drive capacitive loads without oscillation?
TLV2475CPWPR remains stable with capacitive loads ≤10pF directly at the output. For larger loads (e.g., ADC input capacitance), TI recommends adding a series RNULL resistor (≥20Ω) between the output and load, as shown in Figure 42 of the datasheet. This preserves phase margin >60° even with 1000pF loads and prevents ringing in precision sampling circuits.
What is the input offset voltage drift specification for TLV2475CPWPR?
The TLV2475CPWPR has a temperature coefficient of input offset voltage (αVIO) of 0.4μV/°C maximum. Over a –40°C to +125°C range, this contributes ≤66μV of additional offset beyond the 250μV typical room-temperature value - ensuring predictable, low-drift performance in uncalibrated industrial sensor interfaces.
