Product details
Overview
TLV2475AIPWPR 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. It operates from 2.7V to 6V and is optimized for low-voltage sensor signal conditioning in portable medical devices and battery-powered data acquisition systems.
For engineers reviewing the TLV2475AIPWPR datasheet, TLV2475AIPWPR pinout, TLV2475AIPWPR application, or TLV2475AIPWPR equivalent, key selection criteria include its 350nA/channel shutdown current at 3V, rail-to-rail I/O swing enabling full dynamic range in single-supply 3V systems, and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The TLV2475AIPWPR integrates four independent amplifiers sharing a common shutdown control (pins 3/4SHDN), each featuring CMOS input stage with 2.5pA bias current and rail-to-rail output stage capable of sourcing/sinking ±35mA while maintaining 180mV headroom to supply rails. Its 2.8MHz gain-bandwidth product and 1.5V/μs slew rate support moderate-speed signal buffering and filtering.
Shutdown mode places outputs in high-impedance state and reduces per-channel supply current to 350nA at 3V (1000nA at 5V), with turn-on/off times of 5μs and 250ns respectively. The device is fully specified across –40°C to +125°C and supports single-supply operation down to 2.7V without performance degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2475CDR | Same electrical specs but commercial temperature range (0°C to +70°C); SOIC-14 package instead of TSSOP-16. | Suitable for cost-sensitive consumer electronics where extended temperature rating is unnecessary. | Select when board space is less constrained and industrial temp grade is not required. |
| OPA4340UA | Higher precision (125μV max VIO), lower noise (12nV/√Hz), but higher supply current (750μA/ch) and no shutdown function. | Better for high-resolution data loggers where offset drift matters more than power savings. | Choose when ultra-low offset and noise outweigh shutdown capability and quiescent current. |
Compared with TLV2475CDR, TLV2475AIPWPR offers guaranteed operation to +125°C and smaller TSSOP-16 footprint; versus OPA4340UA, it trades 125μV offset for 350nA shutdown current and integrated power gating-critical for energy harvesting and battery longevity.

FAQ
What is the maximum load capacitance the TLV2475AIPWPR can drive without instability?
The TLV2475AIPWPR maintains ≥61° phase margin with up to 1000pF capacitive load when configured as unity-gain follower with RL = 10kΩ. For loads >10pF, TI recommends adding a 20Ω series resistor (RNULL) between output and load to ensure stability, as documented in Figure 42 of the SLOS232E datasheet. This applies to all four channels of TLV2475AIPWPR identically.
Does the TLV2475AIPWPR support true single-supply operation down to 2.7V?
Yes, the TLV2475AIPWPR is fully specified from 2.7V to 6V supply voltage, with rail-to-rail input common-mode range (0V to VDD) and output swing within 180mV of both rails at 3V. Electrical characteristics including 2.8MHz GBW, 600μA/channel IDD, and 250μV VIO are guaranteed across this range per the SLOS232E datasheet revision July 2007.
How does the shutdown functionality work on the TLV2475AIPWPR?
The TLV2475AIPWPR uses two dedicated shutdown pins: pin 4 (1/2SHDN) controls channels 1 and 2, while pin 12 (3/4SHDN) controls channels 3 and 4. Driving either pin <0.8V places associated outputs in high-impedance state and reduces per-channel supply current to 350nA at 3V. Both pins must be >2V to enable all four channels simultaneously.
What is the thermal performance of the TLV2475AIPWPR in TSSOP-16 package?
The TLV2475AIPWPR in TSSOP-16 (PWP) package has θJA = 29.7°C/W and θJC = 2.07°C/W per the SLOS232E datasheet. At maximum dissipation of 4.21W (derated per ambient temperature), junction temperature rise is limited to <125°C in typical 2-layer PCB layouts with 1in² copper pour, supporting reliable operation in industrial enclosures up to +85°C ambient.
Can the TLV2475AIPWPR replace older TLV2475 variants in existing designs?
Yes, TLV2475AIPWPR is a direct replacement for TLV2475IPWP and TLV2475AIPWP with identical pinout, electrical specifications, and thermal characteristics. The 'A' suffix denotes improved input offset voltage (1600μV max vs 2400μV for non-A versions), and 'R' suffix indicates tape-and-reel packaging-both compatible with standard SMT assembly processes used for TLV2475AIPWPR.
