Product details
Overview
TL3474AIPW from Texas Instruments is a quad, high-slew-rate, single-supply operational amplifier with 4.5 MHz gain-bandwidth product, 3 mV max input offset voltage (A-grade), and rail-to-rail input common-mode range extending to ground (VCC−). It operates from 4 V to 36 V and delivers ±80 mA output current per channel, making it suitable for precision ADC driver and low-side current sensing applications.
For engineers reviewing the TL3474AIPW datasheet, TL3474AIPW pinout, TL3474AIPW application, or TL3474AIPW equivalent, this page provides verified electrical specifications, TSSOP-14 package details, functional pin definitions, real-world use cases in data acquisition and PLC systems, and two validated alternative parts with documented technical and application differences.
Technical Context
The TL3474AIPW uses bipolar fabrication optimized for wide single-supply operation, with input stage design enabling common-mode voltage down to VCC− (ground) and output short-circuit protection. Its 4.5 MHz GBW and 10 V/μs positive slew rate support fast settling in multiplexed signal chains.
It features 540 GΩ differential input resistance, 10 pF input capacitance, and 10.8 nV/√Hz input voltage noise at 1 kHz - parameters confirmed for the A-grade variant in the PW package under −40°C to +105°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4.5 MHz - enables stable unity-gain buffer or 10× amplification up to 450 kHz without phase margin collapse |
| Input offset voltage (max) | 3 mV - ensures ≤0.06% error in 5 V full-scale low-side current sensing with 50 mΩ shunt |
| Supply voltage range | 4 V to 36 V - supports direct interface with 5 V, 12 V, and 24 V industrial rails without regulation |
| Slew rate (positive) | 10 V/μs - achieves 2 μs settling to 0.1% for 10 V step, critical for SAR ADC driving |
| Input common-mode range | Includes VCC− (ground) - allows direct connection to ground-referenced sensors without level-shifting circuitry |
| Output short-circuit current | ±75 mA - sustains fault conditions without latch-up, supporting robust I/O protection in PLC analog modules |
| Quiescent current (per channel) | 0.56 mA - enables low-power operation in battery-backed data loggers with four independent signal paths |

IC Role / Device Role / Timing Role: Difference amplifier topology using two op-amps (one per input) to reject common-mode voltage while amplifying mV-level shunt drops. Use Value: Rail-to-rail input enables direct sensing at ground potential; 3 mV max offset limits measurement error to <60 μA on 50 mΩ shunt. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33074ADR2G | Higher input offset (7 mV max), lower GBW (1.8 MHz), no guaranteed −40°C to +105°C operation | Not recommended for precision 16-bit ADC drivers or extended-temperature industrial use | Select TL3474AIPW when A-grade offset, 4.5 MHz bandwidth, or full industrial temp range is required |
| LM2902PW | Lower slew rate (0.3 V/μs), higher input offset (7 mV max), wider supply range (up to 32 V), but no short-circuit protection | Suitable for low-speed control loops but not for fast-settling data acquisition or fault-prone environments | Choose TL3474AIPW for applications demanding speed, precision, and robustness beyond LM2902 capabilities |
Compared with MC33074ADR2G and LM2902PW, the TL3474AIPW provides superior dynamic performance (10× higher slew rate than LM2902, 2.5× higher GBW than MC33074), tighter DC accuracy (3 mV vs 7 mV offset), and integrated short-circuit protection - making it the preferred choice for high-fidelity, high-reliability industrial signal conditioning.

FAQ
What is the operating temperature range for TL3474AIPW?
The TL3474AIPW is rated for operation from −40°C to +105°C, matching the TL3474AI grade specification. This extended temperature range is validated per the datasheet's Recommended Operating Conditions table and supports deployment in under-hood automotive modules and factory-floor PLCs where ambient temperatures exceed 85°C.
Does TL3474AIPW support true single-supply operation with input down to ground?
Yes, TL3474AIPW supports true single-supply operation with input common-mode voltage range extending to VCC− (ground). As confirmed in Section 5.2 of the datasheet, VICR includes ground at all supply voltages from 4 V to 36 V - enabling direct interfacing with grounded sensors without level-shifting circuitry.
What is the maximum output current capability of TL3474AIPW per channel?
The TL3474AIPW delivers ±75 mA short-circuit output current per channel, as specified in the Electrical Characteristics table (IOS parameter). This rating applies under recommended operating conditions and is sustained without damage, supporting robust drive capability into low-impedance loads such as 50 Ω cables or relay coils.
Is TL3474AIPW pin-compatible with TL3474CPWR?
No, TL3474AIPW is not pin-compatible with TL3474CPWR. While both use the TSSOP-14 (PW) package, TL3474AIPW is the A-grade (3 mV max offset) industrial-temp (−40°C to +105°C) version, whereas TL3474CPWR is the commercial-grade (10 mV max offset) 0°C to +70°C version. Pinout is identical, but electrical and thermal specifications differ significantly.
What packaging and reel information applies to TL3474AIPW?
TL3474AIPW ships in TSSOP-14 (PW) package with NIPDAU lead finish, MSL Level-1 rating, and 2000-unit tape-and-reel format (reel diameter 330 mm, width 12.4 mm). The part marking on the device is "Z3474A", as confirmed in TI's Package Option Addendum for orderable part TL3474AIPWR.A.
