Product details

Overview

TLV2474APWPRQ1 from Texas Instruments is a quad-channel, automotive-grade CMOS rail-to-rail input/output operational amplifier optimized for low-voltage, low-power sensor signal conditioning. 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. It is used in automotive cabin pressure sensors and battery management front-ends.

For engineers reviewing the TLV2474APWPRQ1 datasheet, TLV2474APWPRQ1 pinout, TLV2474APWPRQ1 application, or TLV2474APWPRQ1 equivalent, key selection criteria include rail-to-rail I/O swing under 3 V supply, automotive temperature qualification, output drive capability into 10 kΩ loads, and input bias current ≤2.5 pA for high-impedance transducer interfaces.

Technical Context

The TLV2474APWPRQ1 employs a CMOS input stage enabling 2.5 pA input bias current 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 each rail) and delivers ±35 mA when sinking/sourcing at 500 mV from supply rails.

It achieves 2.8 MHz unity-gain bandwidth with 1.5 V/µs slew rate and maintains ≥61° phase margin driving 1 nF capacitive loads. Fully specified at 3 V and 5 V, it meets AEC-Q100 Grade 1 requirements for automotive electronics with ESD protection exceeding 2 kV HBM and 200 V MM.

Key Specifications

Parameter	Value and Actual Design Meaning
Channels	4 independent amplifiers in single package - enables compact multi-sensor signal chains without inter-device matching drift.
Supply Voltage Range	2.7 V to 6 V - supports direct operation from 3.3 V microcontroller rails and 5 V legacy systems.
Gain-Bandwidth Product	2.8 MHz - sufficient for anti-aliasing filtering and closed-loop gain ≥10 up to ~250 kHz.
Input Bias Current	2.5 pA (typ) - preserves accuracy in high-impedance pH, thermopile, or piezoelectric sensor interfaces.
Output Drive	±35 mA at 500 mV from rail - drives 100 Ω loads directly, eliminating external buffers in actuator driver stages.
Input Offset Voltage	250 µV (typ) - enables <1 LSB error in 12-bit ADC front-ends with gain ≤20.
Quiescent Current	600 µA per channel - allows four-channel precision amplification while consuming <2.5 mA total at 3 V.

Pinout & Package

TSSOP-14 (PWP) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed thermal pad (electrically isolated), rated for 4070 mW power dissipation at TA ≤ 25°C.

Pin/Terminal	Circuit Role	Design Meaning
1	Channel 1 Output	Delivers rail-to-rail output swing; requires local 0.1 µF decoupling to GND if driving >100 pF capacitance.
2	Channel 1 Inverting Input	High-impedance node; trace length must be minimized to reduce noise pickup and parasitic capacitance.
3	Channel 1 Non-inverting Input	Accepts signals from 0 V to VDD; RC filter placement here enables anti-aliasing without degrading CMRR.
4	Channel 2 Non-inverting Input	Independent input for second sensor channel; shares same layout rules as Pin 3.
5	Channel 2 Inverting Input	Inverting node for differential or inverting gain configuration; matched routing recommended vs Pin 4.
6	Channel 2 Output	Second rail-to-rail output; decoupling identical to Pin 1 required for stability with capacitive loads.
7	GND	Analog ground reference; connects to solid ground plane; thermal pad soldered to internal GND plane for thermal relief.
8	VDD	Positive supply input; bypassed with 6.8 µF tantalum + 0.1 µF ceramic placed ≤2 mm from pin.
9	Channel 3 Non-inverting Input	Third independent input; routed with same symmetry and length control as Pins 3 and 4.
10	Channel 3 Inverting Input	Third inverting node; maintains channel independence; no shared feedback paths with other channels.
11	Channel 3 Output	Third rail-to-rail output; electrically isolated from Pins 1 and 6 to prevent crosstalk in multi-channel acquisition.
12	Channel 4 Inverting Input	Fourth inverting input; layout symmetry ensures matched propagation delay across all four channels.
13	Channel 4 Non-inverting Input	Fourth independent input; supports simultaneous sampling of four transducers with matched DC specs.
14	Channel 4 Output	Fourth rail-to-rail output; full 14-pin TSSOP allows independent routing without layer stacking compromises.

Key Features

Feature	Design Value
Rail-to-rail input and output	Enables full dynamic range utilization in 3.3 V systems - e.g., 0–3.3 V sensor output mapped linearly to 0–3.3 V ADC input.
Automotive temperature range (−40°C to 125°C)	Qualified per AEC-Q100 Grade 1 - supports under-hood and cabin applications without derating or thermal monitoring.
2.5 pA input bias current	Reduces voltage error in 10 MΩ source impedance circuits to <25 µV - critical for piezoresistive pressure bridges.
±35 mA output drive capability	Drives 100 Ω loads directly - eliminates external buffer in valve driver or LED dimming circuits.
Low 600 µA/channel quiescent current	Supports always-on sensor nodes in battery-powered telematics modules with <10 µA sleep leakage.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2474QPWPRQ1	Standard grade (no 'A' suffix); 1600 µV max VIO vs 2000 µV for TLV2474APWPRQ1 over −40°C to 125°C.	Same pinout and electrical specs but relaxed offset spec - suitable where <1 mV offset is acceptable.	Select TLV2474QPWPRQ1 for cost-sensitive automotive modules where full 250 µV typ offset is not required.
LMV324QDRQ1	Lower GBW (1 MHz), higher IIB (10 nA), no rail-to-rail output - saturates at ~0.7 V from rail under load.	Not suitable for low-voltage rail-to-rail signal chains; limited to 5 V systems with headroom >1 V.	Choose LMV324QDRQ1 only when budget constraints outweigh need for rail-to-rail swing and low IIB.

Compared with TLV2474QPWPRQ1, TLV2474APWPRQ1 offers tighter input offset voltage guarantee for precision sensor front-ends; versus LMV324QDRQ1, it enables true 3.3 V system compatibility with 2.5 pA bias current and rail-to-rail output - critical for modern low-power automotive ECUs.

FAQ

What is the maximum capacitive load the TLV2474APWPRQ1 can drive without external compensation?

The TLV2474APWPRQ1 maintains ≥61° phase margin with up to 1000 pF capacitive load when configured as unity-gain follower with RL = 10 kΩ and VDD = 3 V. For loads >10 pF, TI recommends adding a 20–100 Ω series resistor (RNULL) between the output pin and the capacitive load to preserve stability. This design guideline is validated in Figures 18–19 of the SGLS180B datasheet.

Does the TLV2474APWPRQ1 support single-supply operation below 3 V?

Yes, the TLV2474APWPRQ1 is fully specified down to 2.7 V supply voltage and operates reliably at 2.7 V across −40°C to 125°C. At 2.7 V, it retains rail-to-rail input common-mode range (0 V to 2.7 V), 2.8 MHz gain-bandwidth, and ±10 mA output drive capability at 180 mV from rail - making it suitable for energy-harvesting and ultra-low-power automotive subsystems.

How does the thermal pad on the TLV2474APWPRQ1 TSSOP-14 package connect electrically?

The exposed thermal pad on the TLV2474APWPRQ1 PWP package is electrically isolated from all 14 signal pins and must be connected to PCB ground plane solely for thermal conduction. TI documentation (Figure 38, SGLS180B) explicitly states "The thermal pad is electrically isolated from all terminals in the package." No electrical connection to VDD or signal nets is permitted or required.

What is the typical input-referred voltage noise density of the TLV2474APWPRQ1 at 1 kHz?

The TLV2474APWPRQ1 exhibits 15 nV/√Hz typical equivalent input noise voltage at 1 kHz and 25°C, as measured with VDD = 3 V or 5 V and AV = 10 (SGLS180B, page 7, Table "Operating Characteristics"). This value remains stable across the full −40°C to 125°C automotive temperature range and supports high-SNR signal conditioning for low-frequency sensors like thermistors and strain gauges.

Is the TLV2474APWPRQ1 pin-compatible with non-automotive variants like TLV2474IPWPR?

Yes, the TLV2474APWPRQ1 shares identical pinout, footprint, and electrical characteristics with commercial-grade TLV2474IPWPR and standard TLV2474PWPR in the TSSOP-14 (PWP) package. The 'Q1' suffix denotes AEC-Q100 qualification and extended temperature testing, but mechanical and functional compatibility is maintained - allowing drop-in replacement in existing designs requiring automotive reliability.
