Product details
Overview
TLV2422QDR from Texas Instruments is a dual rail-to-rail output, micropower operational amplifier optimized for automotive-grade operation (–40°C to 125°C). It delivers 50 µA per channel supply current, 18 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing with ±0.25 V beyond rails on 5-V supply - enabling high-precision signal conditioning in battery-powered sensor front-ends and ADC interface circuits.
For engineers reviewing the TLV2422QDR datasheet, TLV2422QDR pinout, TLV2422QDR application, or TLV2422QDR equivalent, key selection criteria include its extended common-mode input range (0 V to 4.5 V min), absence of phase inversion near supply rails, 950 µV max input offset voltage (TLV2422AQ variant), low 1 pA typical input bias current, and Q-temp automotive qualification per AEC-Q100.
Technical Context
The TLV2422QDR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining wide common-mode input voltage range (0 V to VDD – 0.8 V) and no phase inversion - critical for single-supply transducer amplification. Its input stage avoids CMOS gate oxide stress by operating within safe input voltage limits relative to VDD+ and VDD–.
It features micropower architecture with 100–150 µA total supply current (25°C, no load), 46–52 kHz gain-bandwidth product, and 0.008 V/µs slew rate - balancing bandwidth, power, and precision for low-frequency analog signal chains in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-cell Li-ion, dual AA/AAA, and industrial 5-V/3.3-V rails without level-shifting. |
| Rail-to-Rail Output Swing | Within 0.04 V of VDD+ and 0.05 V of VDD– at 100 µA load - maximizes dynamic range into 12-bit+ ADCs. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C (TLV2422AQ grade) - enables <1 LSB error in 12-bit systems with 2.5-V reference. |
| Input Bias Current (typ) | 1 pA - preserves signal integrity from high-impedance sources like piezoelectric sensors or pH electrodes. |
| Supply Current per Channel | 50 µA - allows continuous operation for >1 year on a 220 mAh coin cell in always-on monitoring nodes. |
| Common-Mode Input Range | 0 V to 4.2 V (min) on 5-V supply - accepts ground-referenced inputs without level-shifting circuitry. |
| Output Drive Capability | ±50 mA short-circuit current; drives 600-Ω loads - interfaces directly with telecom line drivers or analog multiplexers. |
Pinout & Package
TLV2422QDR is housed in an 8-pin SOIC (D) package with standard dual-opamp pinout and exposed pad not present. Pin functions are validated per TI SLOS199C datasheet Figure 2 (D package top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Inverting amplifier output - rail-to-rail capable; connects directly to ADC input or filter network. |
| 2 | IN1– | Inverting input - high-impedance node; requires matched trace routing to minimize offset drift. |
| 3 | IN1+ | Non-inverting input - accepts DC-biased sensor signals up to VDD–0.8 V without clipping. |
| 4 | VDD– / GND | Negative supply or ground reference - shared return path for both amplifiers; decoupling required. |
| 5 | VDD+ | Positive supply - accepts 2.7–10 V; must be bypassed with 0.1 µF ceramic capacitor near pin. |
| 6 | OUT2 | Second amplifier output - independent channel; enables dual-sensor buffering or differential drive. |
| 7 | IN2– | Second inverting input - identical electrical behavior to IN1–; supports matched dual-channel designs. |
| 8 | IN2+ | Second non-inverting input - enables simultaneous processing of two analog signals with same biasing. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Eliminates output glitches when common-mode input reaches VDD or GND - essential for sensor signal integrity in motor control feedback loops. |
| Extended common-mode input range | 0 V to VDD–0.8 V enables direct connection of ground-referenced thermistors or bridge sensors without external bias resistors. |
| Low input voltage noise | 18 nV/√Hz at 1 kHz supports accurate amplification of µV-level signals from strain gauges or medical biosensors. |
| Q-temp automotive qualification | AEC-Q100 Grade 2 (–40°C to +125°C) ensures reliability in engine control units, ADAS sensor modules, and under-hood electronics. |
| Micropower operation | 100 µA total IDD (25°C) enables ultra-low-power wake-up circuits and energy-harvesting applications with minimal quiescent loss. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2422AIPWLE | TSSOP-8 package; identical electrical specs but rated for –40°C to 85°C only. | Suitable for commercial/industrial temperature range; not qualified for automotive under-hood use. | Select when board space is constrained and automotive temp range is unnecessary. |
| LMV358QDR | Higher supply current (150 µA/ch), wider GBW (1 MHz), but no guaranteed rail-to-rail output swing at full load. | Better for higher-speed signal paths; less suitable for precision low-voltage ADC interfacing. | Choose when bandwidth >100 kHz is required and micropower is secondary. |
Compared with TLV2422AIPWLE, TLV2422QDR provides extended temperature operation and automotive qualification; compared with LMV358QDR, it offers lower power and guaranteed rail-to-rail output at cost of bandwidth - making TLV2422QDR optimal for precision, low-power, high-reliability sensor interfaces.

FAQ
What is the maximum operating temperature range for TLV2422QDR?
The TLV2422QDR is qualified for operation from –40°C to +125°C, meeting AEC-Q100 Grade 2 requirements for automotive under-hood applications. This rating is confirmed in the "recommended operating conditions" table of the SLOS199C datasheet, where Q-suffix devices specify TA = –40°C to 125°C.
Does TLV2422QDR support true rail-to-rail input operation?
No - TLV2422QDR features rail-to-rail *output* swing but has an extended common-mode input range (0 V to VDD–0.8 V), not full rail-to-rail input. It does not accept inputs at VDD+ or below GND, unlike dedicated rail-to-rail input op-amps such as the TLV9002.
Can TLV2422QDR drive a 10-kΩ load while maintaining rail-to-rail output?
Yes - the TLV2422QDR sustains rail-to-rail output swing (within 0.05 V of rails) when driving ≥10-kΩ loads at room temperature. Output voltage specifications (VOH/VOL) in the datasheet are tested with RL = 10 kΩ, confirming full dynamic range preservation for typical ADC interface loads.
Is TLV2422QDR pin-compatible with other dual op-amps in SOIC-8 packages?
TLV2422QDR follows the industry-standard dual op-amp pinout (pin 1 = OUT1, pin 2 = IN1–, pin 3 = IN1+, pin 4 = V–, pin 5 = V+, pin 6 = OUT2, pin 7 = IN2–, pin 8 = IN2+), matching LM358, TLV2372, and many others - enabling drop-in replacement where electrical specs align.
What is the typical input offset voltage drift over temperature for TLV2422QDR?
The TLV2422QDR exhibits a temperature coefficient of input offset voltage (αVIO) of 2 µV/°C, consistent across all variants including Q- and AQ-grade parts. This value is specified in the "electrical characteristics" tables for both 3-V and 5-V operation and applies over the full –40°C to 125°C range.
