Product details
Overview
TLV2422QDRG4Q1 from Texas Instruments is a dual, micropower, rail-to-rail output operational amplifier qualified for automotive applications (AEC-Q100 Grade 1). It delivers 50 µA per channel supply current, 18 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing with 600-Ω load drive capability - enabling precision signal conditioning in battery-powered sensor interfaces and ADC front-ends.
For engineers reviewing the TLV2422QDRG4Q1 datasheet, TLV2422QDRG4Q1 pinout, TLV2422QDRG4Q1 application, or TLV2422QDRG4Q1 equivalent, key selection criteria include its extended common-mode input range (0 V to 4.5 V on 5-V supply), absence of phase inversion, low 950 µV max input offset voltage (TLV2422A variant), and guaranteed operation from −40°C to 125°C.
Technical Context
The TLV2422QDRG4Q1 employs Advanced LinCMOS™ process technology to achieve high input impedance (>1012 Ω), ultra-low input bias current (1 pA typ), and stable rail-to-rail output performance without phase inversion near supply rails. Its architecture supports single-supply operation down to 2.7 V while maintaining 70 dB CMRR and 80 dB PSRR across temperature.
It features internal compensation for unity-gain stability with capacitive loads up to 100 pF, delivers 0.02 V/µs slew rate at 5 V, and achieves 52 kHz gain-bandwidth product - optimized for low-frequency precision amplification rather than high-speed signal processing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports wide-input automotive and industrial power rails without external regulation. |
| Input Offset Voltage (max) | 2.5 mV at TA = 25°C - enables accurate DC-coupled amplification in sensor signal chains without trimming. |
| Supply Current per Channel | 150 µA max (full temp range) - ensures multi-year battery life in always-on monitoring systems. |
| Common-Mode Input Range | 0 V to VDD−0.8 V - accepts ground-referenced inputs on single 5-V supply, simplifying level-shifting. |
| Output Drive Capability | ±50 mA short-circuit current; drives 600-Ω loads to rail - interfaces directly with telecom line drivers and SAR ADC reference buffers. |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - preserves SNR in high-impedance piezoelectric transducer and thermopile amplifiers. |
| Operating Temperature | −40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and powertrain electronics. |
Pinout & Package
TLV2422QDRG4Q1 is housed in an 8-pin SOIC (D) package with standard 1.27-mm pitch, JEDEC MS-012AC compliant, and RoHS-compliant NiPdAu lead finish. MSL Level-1 rating allows unlimited floor life before reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Amplifier 1 output | Delivers rail-to-rail output swing; capable of sourcing/sinking ±50 mA. |
| 1IN− | Inverting input, Amp 1 | High-impedance node (1012 Ω); accepts differential signals up to VDD−0.8 V. |
| 1IN+ | Non-inverting input, Amp 1 | Same common-mode range as 1IN−; no phase inversion when driven to rails. |
| VDD−/GND | Negative supply / ground reference | Single-supply operation uses this pin as system ground; dual-supply mode connects to negative rail. |
| VDD+ | Positive supply | Accepts 2.7–10 V; supplies both amplifiers; PSRR ≥ 80 dB suppresses supply ripple. |
| 2OUT | Amplifier 2 output | Independent rail-to-rail output; electrically isolated from 1OUT for dual-channel operation. |
| 2IN− | Inverting input, Amp 2 | Matches 1IN− specs; enables dual-sensor conditioning or active filter stages. |
| 2IN+ | Non-inverting input, Amp 2 | Identical performance to 1IN+; supports independent gain configurations per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 50 mV of VDD+ and VDD− on 5-V supply - maximizes dynamic range into 12-bit+ ADCs. |
| No phase inversion | Stable operation even when common-mode input reaches supply rails - eliminates latch-up risk in overvoltage conditions. |
| Extended common-mode input range | 0 V to 4.5 V (min) on 5-V supply - enables direct interfacing with 0–5 V sensors and DAC outputs. |
| Automotive qualification | AEC-Q100 Grade 1 (−40°C to +125°C) - certified for engine control, body electronics, and ADAS subsystems. |
| Low input bias current | 1 pA typical - prevents signal degradation in high-Z pH electrodes, photodiode transimpedance amps, and piezo sensors. |
| Micropower operation | 100 µA typical per channel at 25°C - reduces thermal drift and enables compact PCB layout in space-constrained modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2422AQDRQ1 | Lower max input offset voltage (950 µV vs. 2.5 mV) at 25°C; otherwise identical pinout, specs, and qualification. | Suitable where tighter DC accuracy is required (e.g., precision weigh scales), but higher cost and lower volume availability. | Select TLV2422AQDRQ1 only if offset-critical calibration budgets demand <1 mV error at room temperature. |
| MCP6022-E/SN | Higher supply current (120 µA/ch typ), wider GBW (1 MHz), but no AEC-Q100 qualification and narrower common-mode range (VSS to VDD−1.2 V). | Applicable in commercial-grade instrumentation, but not automotive or extended-temp industrial use. | Choose MCP6022-E/SN only for non-automotive designs requiring faster settling or higher bandwidth, accepting reduced temp range and no automotive certification. |
Compared with TLV2422AQDRQ1, the TLV2422QDRG4Q1 trades offset accuracy for broader availability and cost efficiency; versus MCP6022-E/SN, it provides guaranteed automotive reliability and superior rail-compatible input behavior at the expense of speed.

FAQ
What is the maximum operating temperature for TLV2422QDRG4Q1?
The TLV2422QDRG4Q1 is rated for continuous operation from −40°C to +125°C, meeting AEC-Q100 Grade 1 requirements for automotive under-hood applications. This specification is validated across all electrical parameters in the datasheet's "Recommended Operating Conditions" table and confirmed in the "Package Option Addendum" for the Q1 suffix part.
Does TLV2422QDRG4Q1 support true rail-to-rail input?
No - TLV2422QDRG4Q1 provides rail-to-rail *output* swing but has an extended common-mode input range (0 V to VDD−0.8 V on 5-V supply), not full rail-to-rail input. It avoids phase inversion when inputs approach the rails, distinguishing it from basic CMOS op-amps, but does not accept inputs beyond VDD−0.8 V or below ground.
Is TLV2422QDRG4Q1 pin-compatible with TLV2422AQDRQ1?
Yes - TLV2422QDRG4Q1 and TLV2422AQDRQ1 share identical SOIC-8 (D) packaging, pinout, and footprint. Both are drop-in replacements electrically and mechanically; the only functional difference is the tighter input offset voltage spec (950 µV max) of the 'A' variant.
What load capacitance can TLV2422QDRG4Q1 safely drive without oscillation?
The TLV2422QDRG4Q1 is unity-gain stable with capacitive loads up to 100 pF, as verified in Figure 31 and Figure 48 of the datasheet. Driving larger capacitive loads (e.g., >200 pF) requires isolation resistors or external compensation to maintain ≥45° phase margin.
How does the input bias current of TLV2422QDRG4Q1 affect high-impedance sensor interfaces?
With 1 pA typical input bias current, TLV2422QDRG4Q1 introduces negligible voltage error across sensor impedances up to 10 GΩ - critical for piezoelectric accelerometers, pH electrodes, and photodiode transimpedance amplifiers where leakage currents degrade accuracy and stability.
