Product details

Overview

TLV2474QPWPRQ1 from Texas Instruments is a quad-channel, automotive-grade CMOS rail-to-rail input/output operational amplifier optimized for low-voltage sensor signal conditioning and data acquisition. It delivers 2.8 MHz gain-bandwidth, 600 µA/channel supply current, ±35 mA output drive at 500 mV from rail, 250 µV typical input offset voltage, and operates across −40°C to 125°C.

For engineers reviewing the TLV2474QPWPRQ1 datasheet, TLV2474QPWPRQ1 pinout, TLV2474QPWPRQ1 application, or TLV2474QPWPRQ1 equivalent, key selection criteria include rail-to-rail I/O swing in 2.7–6 V systems, high output current capability under automotive temperature stress, low input bias current (2.5 pA), and verified AEC-Q100 Grade 1 qualification.

Technical Context

The TLV2474QPWPRQ1 employs a CMOS input stage enabling ultra-low input bias current (2.5 pA) and rail-to-rail common-mode input range (0 V to VDD). Its output stage supports true rail-to-rail swing under 10 mA load (to within 180 mV of rails) and delivers ±35 mA when operating 500 mV from supply rails - resolving micropower op-amp drive limitations.

It features 2.8 MHz unity-gain bandwidth with 1.5 V/µs slew rate, 84 dB CMRR at 5 V, and 92 dB large-signal voltage gain (AVD) at 3 V, all fully specified across −40°C to 125°C. ESD protection exceeds 2000 V (HBM) and 200 V (MM), meeting automotive robustness requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
Channels	4 independent amplifiers in single package - enables compact multi-sensor front-end designs without inter-device matching drift.
Supply Voltage Range	2.7 V to 6 V - supports direct operation from single-cell Li-ion, 3.3 V, or 5 V rails without level-shifting.
Gain-Bandwidth Product	2.8 MHz - enables stable closed-loop gain up to ~10× at 280 kHz, suitable for anti-aliasing and sensor signal filtering.
Input Offset Voltage (typ)	250 µV - ensures ≤0.5% error in 50 mV full-scale bridge sensor outputs without trimming.

7	Channel 2 Output	Second independent output; capable of sourcing/sinking ±35 mA for driving analog multiplexers or LED indicators.
8	VDD	Positive supply rail; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling per datasheet layout guidelines.
9	Channel 3 Output	Third amplifier output; identical AC/DC specs enable synchronized multi-path signal conditioning.
10	Channel 3 Inverting Input	Third input node; same 2.5 pA bias current enables precision current-sense shunt monitoring.
11	Channel 3 Non-Inverting Input	Third high-Z input; rail-to-rail input allows direct interface with thermistor voltage dividers across full VDD range.
12	Channel 4 Non-Inverting Input	Fourth input; supports redundant sensor architectures or multi-stage filtering without external components.
13	Channel 4 Inverting Input	Fourth differential input; matched performance enables simultaneous sampling of four sensor channels.
14	Channel 4 Output	Fourth rail-to-rail output; full 2.8 MHz bandwidth supports real-time control loop feedback paths.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2474QDRQ1	SOP-14 package (D), higher θJA (122.3°C/W vs 30.7°C/W), lower max power dissipation (1022 mW vs 4070 mW).	Less suitable for high-ambient-temperature environments (>85°C) or high-output-current continuous operation.	Select TLV2474QPWPRQ1 when thermal performance or board space constraints favor TSSOP-14 over SOP-14.
LMV324QDRQ1	Lower GBW (1 MHz), higher VIO (1.8 mV typ), no rail-to-rail output (saturates 800 mV from rail), 100 µA/channel supply current.	Targeted at cost-sensitive, low-speed applications where precision and output drive are secondary to ultra-low power.	Choose TLV2474QPWPRQ1 when design requires rail-to-rail swing, 2.8 MHz bandwidth, or ±35 mA drive not available in LMV324QDRQ1.

Compared with TLV2474QDRQ1 and LMV324QDRQ1, TLV2474QPWPRQ1 provides superior thermal efficiency in dense layouts, full rail-to-rail I/O for maximum signal fidelity, and 2.8× higher bandwidth - making it optimal for automotive sensor fusion and medical signal chains demanding accuracy and speed.

FAQ

What is the maximum capacitive load the TLV2474QPWPRQ1 can drive without instability?

The TLV2474QPWPRQ1 exhibits reduced phase margin with capacitive loads >10 pF. Datasheet Figure 18–19 shows phase margin drops below 60° at CL = 100 pF (VDD = 3–5 V). For reliable operation, use a series RNULL ≥20 Ω between output and load capacitance - confirmed effective up to 1 nF in application note SLOU060.

Does the TLV2474QPWPRQ1 support single-supply operation down to 2.7 V?

Yes, the TLV2474QPWPRQ1 is fully specified for single-supply operation from 2.7 V to 6 V across −40°C to 125°C. At 2.7 V, it maintains 2.8 MHz gain-bandwidth, 600 µA/channel supply current, and rail-to-rail input/output swing - enabling direct interface with low-voltage microcontrollers and ADCs.

How does the thermal performance of the TLV2474QPWPRQ1 compare to the SOP-14 variant TLV2474QDRQ1?

The TLV2474QPWPRQ1 in TSSOP-14 (PWP) has θJA = 30.7°C/W and 4070 mW power rating at TA ≤ 25°C, versus θJA = 122.3°C/W and 1022 mW for TLV2474QDRQ1 in SOP-14 (D). This 4× better thermal efficiency allows TLV2474QPWPRQ1 to sustain higher output currents in compact automotive modules without derating.

Is the exposed thermal pad on the TLV2474QPWPRQ1 electrically connected to any internal node?

No, the exposed thermal pad on the TLV2474QPWPRQ1 is electrically isolated from all internal terminals (per datasheet Figure 38 note A). It must be soldered to a PCB copper pour connected to GND or a dedicated thermal plane - but no electrical connection is required for functionality or safety.

What is the typical input offset voltage drift over temperature for TLV2474QPWPRQ1?

The TLV2474QPWPRQ1 has a temperature coefficient of input offset voltage (αVIO) of 0.4 µV/°C (max), as specified in both 3 V and 5 V electrical characteristics tables. Over −40°C to 125°C, this results in ≤66 µV total drift - significantly lower than standard bipolar op-amps and critical for precision automotive sensor calibration.
