Product details
Overview
TLV2474AQDRQ1 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 per channel supply current, ±35 mA output drive at 500 mV from rail, and 250 µV typical input offset voltage across −40°C to 125°C - enabling high-precision analog front-ends in battery-powered automotive ECUs and ADAS sensor modules.
For engineers reviewing the TLV2474AQDRQ1 datasheet, TLV2474AQDRQ1 pinout, TLV2474AQDRQ1 application, or TLV2474AQDRQ1 equivalent, key selection considerations include its AEC-Q100 qualification, rail-to-rail I/O swing at 2.7–6 V supply, 2.5 pA input bias current, thermal performance in SOIC-14 (D) package, and suitability for single-supply data acquisition where dynamic range and micropower operation are critical.
Technical Context
The TLV2474AQDRQ1 employs a CMOS input stage with differential pair architecture delivering ultra-low input bias current (2.5 pA typ) and rail-to-rail common-mode input range (0 V to VDD). Its output stage uses complementary push-pull circuitry enabling true rail-to-rail output swing under load (±10 mA at 180 mV from rail) and high-current sourcing/sinking capability (±35 mA at 500 mV from rail).
This architecture supports stable unity-gain operation with 61° phase margin (CL = 1000 pF, RL = 10 kΩ) and maintains 2.8 MHz gain-bandwidth product across 2.7–6 V supply and full automotive temperature range - making it suitable for precision DC-coupled amplification and low-distortion AC signal paths in safety-critical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct interface with 3.3 V and 5 V automotive microcontrollers without level-shifting. |
| Gain-Bandwidth Product | 2.8 MHz - supports accurate amplification of sensor signals up to ~200 kHz with minimal phase error. |
| Input Bias Current | 2.5 pA (typ) - minimizes voltage error in high-impedance sensor interfaces (e.g., thermocouples, pH electrodes). |
| Output Drive Capability | ±35 mA at 500 mV from rail - drives 10 kΩ loads to within 500 mV of supply rails, reducing need for external buffers. |
| Input Offset Voltage | 250 µV (typ), 2000 µV (max over temp) - ensures <0.1% gain error in 12-bit precision measurement circuits. |
| Slew Rate | 1.5 V/µs (typ at 5 V) - supports clean step response for fast transient detection in motor control feedback loops. |
| CMRR / PSRR | 84 dB / 92 dB (typ at 25°C) - rejects power supply noise and common-mode interference in noisy vehicle environments. |
Pinout & Package
TLV2474AQDRQ1 is housed in a 14-pin SOIC (D) package with exposed thermal pad (non-electrical). Pin 1 is marked with a beveled corner; pin numbering follows standard SOIC convention (counterclockwise from top-left).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Drives external load; rail-to-rail swing supports full dynamic range in single-supply configurations. |
| 1IN− | Channel 1 inverting input | Differential input node; high impedance (10¹² Ω) minimizes loading on preceding stages. |
| 1IN+ | Channel 1 non-inverting input | Accepts reference or sensor signal; common-mode range extends to both supply rails. |
| VDD | Positive supply | Single 2.7–6 V rail powers all four channels; no negative supply required. |
| 2IN+ | Channel 2 non-inverting input | Independent input for second channel; identical electrical specs to Channel 1. |
| 2IN− | Channel 2 inverting input | Supports dual-sensor differential measurement or independent signal path. |
| 2OUT | Channel 2 output | Provides second amplified output; fully isolated from Channel 1 electrically. |
| 4OUT | Channel 4 output | Final output in quad configuration; pin layout allows compact PCB routing for multi-channel designs. |
| 4IN− | Channel 4 inverting input | Enables simultaneous processing of four analog signals (e.g., wheel speed sensors). |
| 4IN+ | Channel 4 non-inverting input | High-impedance input compatible with resistive bridge sensors and current-loop receivers. |
| GND | Analog ground reference | Common return for all channels; requires low-inductance connection to minimize noise coupling. |
| 3IN+ | Channel 3 non-inverting input | Third independent input; supports redundant sensing or multi-axis signal conditioning. |
| 3IN− | Channel 3 inverting input | Matches Channel 1/2/4 specs; enables matched gain configurations across all four op-amps. |
| 3OUT | Channel 3 output | Completes quad functionality; pinout symmetry simplifies layout for balanced analog subsystems. |

FAQ
What is the operating temperature range for TLV2474AQDRQ1?
The TLV2474AQDRQ1 is qualified for automotive applications with a specified operating free-air temperature range of −40°C to +125°C. This range is validated per AEC-Q100 Grade 1 requirements and applies across all electrical parameters in the datasheet, including input offset voltage, gain-bandwidth product, and output drive capability - ensuring reliable operation in engine bay and chassis-mounted ECUs.
Does TLV2474AQDRQ1 support true rail-to-rail input and output?
Yes, TLV2474AQDRQ1 features CMOS input stage and complementary output stage enabling true rail-to-rail operation: common-mode input voltage range spans 0 V to VDD, and output can swing within 180 mV of each rail while sourcing/sinking ±10 mA. At ±35 mA, output reaches within 500 mV of rails - confirmed in both 3 V and 5 V test conditions per datasheet Figures 5–8.
What is the maximum capacitive load TLV2474AQDRQ1 can drive without instability?
TLV2474AQDRQ1 maintains stability with capacitive loads up to 10 pF directly on the output. For loads exceeding 10 pF, the datasheet recommends adding a series null resistor (RNULL ≥ 20 Ω) between the output and load to preserve phase margin - verified by Figure 18–19 showing ≥61° phase margin at CL = 1000 pF when RNULL = 0 Ω is used with appropriate compensation.
How does the input bias current of TLV2474AQDRQ1 affect high-impedance sensor interfaces?
With a typical input bias current of 2.5 pA, TLV2474AQDRQ1 introduces negligible voltage error in high-impedance sensor circuits: for example, a 1 MΩ source impedance contributes only 2.5 µV offset, far below its 250 µV typical input offset voltage. This enables accurate amplification of signals from thermocouples, piezoresistive sensors, and electrochemical cells without active guarding or bias cancellation networks.
Is TLV2474AQDRQ1 pin-compatible with other devices in the TLV247x family?
Yes, TLV2474AQDRQ1 shares identical 14-pin SOIC (D) package pinout with TLV2474QDRQ1, TLV2474QPWPRQ1, and TLV2474APWPRQ1 - all follow the same channel mapping (1OUT, 1IN−, 1IN+, VDD, 2IN+, 2IN−, 2OUT, 4OUT, 4IN−, 4IN+, GND, 3IN+, 3IN−, 3OUT). This allows drop-in replacement within the same package footprint when upgrading from standard to A-grade variants.
