Product details
Overview
TLV2474AIPWR 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 - enabling precision sensor interfacing and portable medical instrumentation.
For engineers reviewing the TLV2474AIPWR datasheet, TLV2474AIPWR pinout, TLV2474AIPWR application, or TLV2474AIPWR equivalent, key selection considerations include its TSSOP-14 package, shutdown-incompatible design (no SHDN pin), rail-to-rail I/O swing down to 2.7V supply, and verified performance across –40°C to +125°C industrial temperature range.
Technical Context
The TLV2474AIPWR implements a CMOS input stage with 2.5pA input bias current and rail-to-rail output stage capable of sourcing/sinking ±35mA while maintaining 180mV headroom to each rail under 10mA load. Its 2.8MHz gain-bandwidth product and 1.5V/μs slew rate support stable unity-gain operation with capacitive loads up to 1000pF when using recommended RNULL series resistance.
Unlike TLV2470/3/5 variants, TLV2474AIPWR lacks a shutdown terminal - confirmed by its pinout (14-pin TSSOP with no SHDN function) and electrical specifications listing only active-mode IDD (600μA/ch) without shutdown current (IDD(SHDN)) data. It operates across 2.7V–6V supply and achieves 84dB CMRR and 92dB PSRR at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - supports direct battery-powered operation from single Li-ion or dual alkaline cells. |
| Gain-Bandwidth Product | 2.8MHz - enables stable closed-loop gain ≥10 up to ~280kHz with minimal phase margin degradation. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 100Ω loads directly without external buffers in data acquisition front-ends. |
| Input Offset Voltage | 250μV (typ) - ensures ≤0.5mV error in 2V full-scale 12-bit ADC interface circuits. |
| Input Bias Current | 2.5pA - minimizes voltage error across high-impedance sensor sources (e.g., pH electrodes, photodiodes). |

Pinout & Package
TSSOP-14 (PWP) package: 4.4mm × 5.0mm body, 0.65mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - rail-to-rail swing, capable of ±35mA drive into resistive loads. |
| 2 | IN1− | Inverting input of Amp 1 - high-impedance CMOS node (10¹²Ω), sensitive to PCB leakage. |
| 3 | IN1+ | Non-inverting input of Amp 1 - matched to IN1− for <250μV offset; requires symmetric layout. |
| 4 | VDD | Positive supply rail - decoupling capacitor (0.1μF) required within 5mm for stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IPWR | Same architecture and specs but rated for 0°C to +70°C only - no extended temperature qualification. | Suitable for commercial-grade consumer devices but not automotive or industrial environments requiring –40°C startup. | Select TLV2474IPWR only if ambient operating temperature stays above 0°C and cost sensitivity outweighs reliability requirements. |
| OPA2340UA/2K5 | Single-supply RRIO quad op-amp with 1MHz GBW, 200μA/ch supply current, and 1.5mV max VIO - lower speed and higher offset than TLV2474AIPWR. | Better suited for ultra-low-power sensor nodes where bandwidth <1MHz is acceptable and sub-1mV offset is not critical. | Choose OPA2340UA/2K5 when extending battery life is paramount and system bandwidth requirements are ≤500kHz. |
Compared with TLV2474IPWR, TLV2474AIPWR provides guaranteed operation down to –40°C and tighter input offset voltage (250μV typ vs unspecified for IPWR), while OPA2340UA/2K5 trades bandwidth and precision for significantly lower quiescent current - making each viable only within distinct thermal, accuracy, and power envelopes.

FAQ
Does TLV2474AIPWR include a shutdown feature?
No, TLV2474AIPWR does not include a shutdown function. Unlike TLV2470/3/5 variants, it has no SHDN pin and no specified shutdown supply current (IDD(SHDN)). The TLV2474AIPWR datasheet omits shutdown-related test conditions and timing parameters, confirming it is an always-on quad op-amp. For power-gated designs, external enable circuitry must be used.
What is the maximum capacitive load TLV2474AIPWR can drive stably?
TLV2474AIPWR remains stable with capacitive loads up to 1000pF when a series null resistor (RNULL) of ≥20Ω is placed between the output and load, as specified in Figure 42 of the datasheet. Without RNULL, oscillation may occur with loads >10pF. Phase margin drops from 68° at 0pF to 61° at 1000pF with RNULL = 20Ω and RL = 10kΩ at 25°C.
Is TLV2474AIPWR pin-compatible with other TLV247x quad variants?
TLV2474AIPWR is pin-compatible with TLV2474CD, TLV2474ID, and TLV2474CPWP in the same TSSOP-14 (PWP) package, sharing identical pinout and footprint. However, it is not pin-compatible with TLV2475 (which includes SHDN pins) or any SOIC/N packages - those use different pin counts and assignments per the FAMILY PACKAGE TABLE.
What is the typical input offset voltage drift over temperature for TLV2474AIPWR?
The TLV2474AIPWR exhibits a typical input offset voltage temperature coefficient (αVIO) of 0.4μV/°C, as confirmed in both 3V and 5V electrical characteristics tables. Over the full –40°C to +125°C range, this results in ≤66μV additional offset drift beyond the 250μV room-temperature value - critical for precision thermocouple or strain gauge amplification where drift dominates long-term accuracy.
Can TLV2474AIPWR operate from a 2.7V single supply while maintaining rail-to-rail output swing?
Yes, TLV2474AIPWR is fully specified at 2.7V supply and maintains rail-to-rail output swing - delivering ±10mA into 10mA loads while swinging to within 180mV of VDD and GND. At 2.7V, output high is typically 2.6V and low is 0.2V under 10mA load (per Electrical Characteristics table, VDD = 3V column extrapolated to 2.7V), preserving >90% of full-scale dynamic range.
