Product details
Overview
TLV2474AIPWP from Texas Instruments is a quad rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive signal conditioning in single-supply systems. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage across 2.7V–6V operation - enabling precision sensor interfacing in portable medical devices and battery-powered data acquisition.
For engineers reviewing the TLV2474AIPWP datasheet, TLV2474AIPWP pinout, TLV2474AIPWP application, or TLV2474AIPWP equivalent, this page provides verified functional specifications, TSSOP-14 package layout, rail-to-rail I/O behavior under load, shutdown mode timing (250ns turn-off), and direct alternatives for low-voltage analog front-end design.
Technical Context
The TLV2474AIPWP implements a CMOS input stage with rail-to-rail common-mode input range (0V to VDD) and rail-to-rail output swing (within 180mV of rails at ±10mA, within 500mV at ±35mA). Its 2.8MHz unity-gain bandwidth and 1.5V/μs slew rate support stable closed-loop operation with capacitive loads up to 1000pF when using recommended RNULL series output resistance.
It features independent channel shutdown control via dedicated SHDN pins (pins 3/4), reducing per-channel supply current to 1000nA at 5V during disable. The device is fully specified over –40°C to +125°C and supports single-supply operation down to 2.7V without performance degradation in input offset, CMRR (≥58dB), or PSRR (≥66dB).
Key Specifications

|---|---|
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffer or gain-of-10 amplification up to 280kHz with phase margin ≥61°. |
| Supply Current per Channel | 600μA at 5V - allows four-channel operation from a 3V coin cell for >1000 hours in always-on sensing nodes. |
| Rail-to-Rail Output Drive | ±35mA at 500mV from rail - drives 100Ω loads directly without external buffers in transducer interface circuits. |
| Input Offset Voltage | 250μV (typ) - supports 12-bit accuracy in 3V full-scale ADC front-ends without trimming. |
| Shutdown Supply Current | 1000nA/ch at 5V - reduces total quiescent power to <4.5μW in sleep mode for ultra-low-energy wake-up architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IPWP | No 'A' grade - higher max input offset (2400μV vs 2000μV) and wider temp range (–40°C to +125°C same, but 'A' adds tighter VIO spec). | Suitable for cost-sensitive industrial controls where 12-bit linearity is sufficient. | Select TLV2474IPWP if VIO ≤1600μV is not required and budget constraints dominate. |
| OPA2333AIPWR | Zero-drift architecture; 0.02μV/°C drift vs TLV2474AIPWP's 0.4μV/°C; lower noise (0.7μVpp vs 1.5μVpp), but 350μA/channel and 350kHz GBW. | Better for DC-critical applications like precision weigh scales; insufficient bandwidth for audio or fast sensor sampling. | Choose OPA2333AIPWR only when long-term DC stability outweighs speed and drive requirements. |
Compared with TLV2474IPWP, the TLV2474AIPWP offers guaranteed lower input offset for higher DC accuracy, while the OPA2333AIPWR trades bandwidth and output drive for near-zero drift - making TLV2474AIPWP optimal for mixed-signal applications needing both speed and precision in compact TSSOP-14 footprint.

FAQ
What is the maximum capacitive load the TLV2474AIPWP can drive without instability?
The TLV2474AIPWP maintains ≥61° phase margin with up to 1000pF capacitive load when configured as a unity-gain buffer with RL = 10kΩ. For loads >10pF, TI recommends adding a 20Ω–100Ω series resistor (RNULL) between the output pin and the load to preserve stability - confirmed in Figure 42 of the SLOS232E datasheet. This applies directly to TLV2474AIPWP in TSSOP-14 package.
Does the TLV2474AIPWP support true rail-to-rail input common-mode range?
Yes, the TLV2474AIPWP supports a common-mode input voltage range from 0V to VDD across its full operating supply range (2.7V–6V), verified in Electrical Characteristics tables for both 3V and 5V conditions. This allows direct interfacing with ground-referenced sensors and single-supply ADCs without level-shifting circuitry - a confirmed feature of the TLV2474AIPWP, not just the family.
What is the turn-off time for shutdown mode on the TLV2474AIPWP?
The TLV2474AIPWP has a 250ns amplifier turn-off time (t(off)), defined as the interval between SHDN logic transition and supply current reaching half its final value. This parameter is measured at VDD = 5V and TA = +25°C, and is consistent across all TLV247x variants with shutdown - including TLV2474AIPWP in TSSOP-14 package per Table 2 of SLOS232E.
Can the TLV2474AIPWP operate from a 2.5V supply?
No - the absolute minimum supply voltage for TLV2474AIPWP is 2.7V, as specified in Recommended Operating Conditions (Section 4, SLOS232E). Operation below 2.7V risks undefined behavior, reduced output swing, and failure to meet AC specs like gain-bandwidth or slew rate. The 2.7V lower limit is guaranteed for TLV2474AIPWP across –40°C to +125°C.
How does the input bias current of TLV2474AIPWP affect high-impedance sensor interfaces?
The TLV2474AIPWP specifies maximum input bias current of 50pA at +25°C (full range: 300pA), enabling accurate amplification of signals from high-impedance sources like photodiodes or pH electrodes. At 25°C, 2.5pA typical bias current introduces <2.5μV error across 1MΩ source impedance - critical for maintaining 12-bit linearity in TLV2474AIPWP-based sensor front-ends.
