Product details
Overview
TLV2422AQD from Texas Instruments is a dual rail-to-rail output, micropower operational amplifier optimized for automotive-grade operation across –40°C to +125°C. It delivers 50 µA per channel supply current, 950 µV max input offset voltage at 25°C, 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 TLV2422AQD datasheet, TLV2422AQD pinout, TLV2422AQD application, or TLV2422AQD equivalent, key selection considerations include its Q-temp automotive qualification, extended common-mode input range (0 V to 4.5 V min on 5-V supply), absence of phase inversion, low 1-pA typical input bias current, and compatibility with single-supply 2.7–10-V operation.
Technical Context
The TLV2422AQD employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing without phase inversion when inputs approach supply rails - a critical advantage over standard CMOS op-amps in high-dynamic-range sensing. Its input stage supports common-mode voltages down to VDD– and up to VDD+ – 0.8 V, enabling direct interfacing with low-voltage microcontrollers and ADC references.
Designed for ultra-low-power operation, the device maintains 46–52 kHz gain-bandwidth product and 0.008 V/µs slew rate while consuming only 100–150 µA per channel at 25°C. Output stage architecture enables ±50 mA short-circuit current capability and stable 600-Ω load driving - validated across full automotive temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports wide-input-voltage operation in automotive 12-V systems with local LDO regulation or direct 3.3/5-V rail use. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables <1 LSB error in 12-bit ADC front-end designs with 5-V reference. |
| Supply Current per Channel | 100–150 µA at 25°C - allows continuous operation for >10 years on a single CR2032 coin cell in wake-up sensor nodes. |
| Input Bias Current (typ) | 1 pA - preserves signal integrity from high-impedance sources like piezoelectric transducers or pH electrodes. |
| Output Drive Capability | 600-Ω load - sufficient to directly drive telecom line drivers or anti-aliasing filter stages without buffer amplification. |
| Input Voltage Noise | 18 nV/√Hz at f = 1 kHz - ensures minimal contribution to system noise floor in precision instrumentation amplifiers. |
| Operating Temperature | –40°C to +125°C - qualified to AEC-Q100 Grade 1 and suitable for under-hood automotive applications. |
Pinout & Package
TLV2422AQD is supplied in an 8-pin SOIC (D) package with standard dual-op-amp pinout and automotive-grade molding compound. The package meets JEDEC MS-012AC and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output A - rail-to-rail swing supports full-scale ADC input utilization. |
| 2 | IN– A | Inverting input A - high-impedance node (10¹² Ω) minimizes loading on sensor bridges or feedback networks. |
| 3 | IN+ A | Non-inverting input A - accepts common-mode signals from 0 V to VDD–0.8 V, enabling single-supply level-shifting. |
| 4 | VDD– / GND | Negative supply / ground reference - shared return path for both amplifiers; requires low-impedance decoupling. |
| 5 | VDD+ | Positive supply - accepts 2.7–10 V; internal regulation ensures stable biasing across automotive load-dump transients. |
| 6 | OUT B | Inverting amplifier output B - independently usable for dual-channel signal paths or differential output configurations. |
| 7 | IN– B | Inverting input B - electrically isolated from IN– A; supports independent feedback loops per channel. |
| 8 | IN+ B | Non-inverting input B - identical electrical characteristics to IN+ A; enables matched dual-sensor conditioning. |
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 for 12-bit+ ADCs without external level-shifting. |
| No phase inversion | Operates linearly as inputs reach supply rails - eliminates output glitches in overvoltage protection circuits or comparator-like threshold detection. |
| Extended common-mode input range | 0 V to 4.5 V (min) on 5-V supply - accommodates direct connection to 3.3-V logic outputs or resistive divider-based sensor references. |
| Micropower consumption | 50 µA per channel - reduces thermal drift and enables always-on monitoring in energy-constrained IoT edge nodes. |
| Low input offset voltage (A-grade) | 950 µV max at 25°C - improves DC accuracy in closed-loop transducer signal chains without trimming components. |
| Automotive Q-temp qualification | AEC-Q100 Grade 1 compliant - certified for reliability in harsh environments including engine control units and ADAS sensor modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2422QD | Same package and pinout; 2.5 mV max VIO (vs. 950 µV for TLV2422AQD); wider offset drift over temperature. | Acceptable where DC accuracy is secondary to cost - e.g., non-critical sensor buffers or audio preamps. | Select TLV2422QD only if system-level calibration compensates for higher offset; not suitable for uncalibrated precision measurement. |
| OPA2333AIDR | Zero-drift architecture; 2 µV max VIO, 0.02 µV/°C drift; higher 17 µA supply current per channel. | Better for sub-16-bit precision systems requiring long-term stability; less suitable for ultra-low-power battery lifetime targets. | Choose OPA2333AIDR when offset drift dominates error budget; avoid when >10× higher supply current compromises power budget. |
Compared with TLV2422AQD, TLV2422QD trades precision for cost in automotive applications, while OPA2333AIDR delivers superior DC accuracy at the expense of micropower operation - making TLV2422AQD optimal for cost-sensitive, battery-limited automotive and industrial sensing where 950 µV offset is sufficient.

FAQ
What is the maximum operating temperature range for TLV2422AQD?
The TLV2422AQD is rated for continuous operation from –40°C to +125°C ambient temperature. This range is validated per AEC-Q100 Grade 1 requirements and supported by full electrical characterization across the entire span, including input offset voltage, supply current, and output drive performance.
Does TLV2422AQD support true rail-to-rail input operation?
No - TLV2422AQD features rail-to-rail *output* swing but not rail-to-rail input. Its common-mode input voltage range extends from VDD– to VDD+ – 0.8 V (e.g., 0 V to 4.2 V on 5-V supply), which exceeds standard CMOS op-amps but does not include the positive rail. Input phase inversion is avoided across this full range.
Can TLV2422AQD drive a 10-kΩ load with rail-to-rail output swing?
Yes - TLV2422AQD maintains rail-to-rail output swing into 10-kΩ loads. Data sheet Figures 1 and 2 confirm VOH ≥ 4.97 V and VOL ≤ 0.04 V at 100 µA load current on 5-V supply, indicating robust performance well within specification for high-impedance ADC inputs and filter stages.
Is TLV2422AQD pin-compatible with other devices in the TLV2422 family?
Yes - TLV2422AQD uses the standard 8-pin SOIC (D) package with identical pinout to TLV2422CD, TLV2422ID, TLV2422QD, and TLV2422AID. All share the same terminal mapping: OUT A, IN– A, IN+ A, VDD–/GND, VDD+, OUT B, IN– B, IN+ B.
What is the typical input bias current of TLV2422AQD and why does it matter?
The typical input bias current of TLV2422AQD is 1 pA at 25°C. This ultra-low value prevents significant voltage drop across high-impedance sensor elements (e.g., pH electrodes or piezoelectric transducers), preserving signal fidelity and eliminating the need for guard traces or active bias cancellation networks.
