Product details
Overview
TLV2422AIDR from Texas Instruments is a dual rail-to-rail output, micropower operational amplifier optimized for low-voltage (2.7 V to 10 V) single- or split-supply operation. 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 - enabling high dynamic range signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2422AIDR datasheet, TLV2422AIDR pinout, TLV2422AIDR application, or TLV2422AIDR equivalent, key selection criteria include its extended common-mode input range (0 V to 4.5 V min with 5-V supply), no phase inversion behavior near rails, 600-Ω output drive capability, and qualification for industrial temperature range (–40°C to 85°C) in SOIC-8 package.
Technical Context
The TLV2422AIDR employs Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and high input impedance (>10¹² Ω), making it suitable for interfacing with high-impedance sources like piezoelectric transducers and pH electrodes. Its rail-to-rail output stage supports full-swing operation into 600-Ω loads without clipping, critical for driving ADC reference buffers and telecom line drivers.
It features no phase inversion when common-mode input approaches either supply rail - eliminating output glitches in level-shifting and active filter applications. The device is fully characterized at 3-V and 5-V supplies, with guaranteed performance across –40°C to 85°C, and exhibits 70 dB minimum CMRR and 80 dB minimum PSRR over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct use with single-cell Li-ion, two-cell alkaline, or regulated 3.3 V/5 V rails. |
| Input Offset Voltage (max) | 950 µV at 25°C - ensures ≤1 mV total error in precision DC-coupled gain stages without trimming. |
| Supply Current per Channel | 100–150 µA (typ 125 µA) - supports multi-year battery life in always-on remote sensors. |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - preserves SNR in low-level analog front-ends for medical and environmental sensing. |
| Common-Mode Input Range | 0 V to VDD – 0.8 V - allows direct interface to ground-referenced signals in single-supply systems. |
| Output Drive Capability | ±50 mA short-circuit current; drives 600-Ω load to rail - eliminates need for external buffer in ADC driver stages. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive cabin applications (non-Q grade). |
Pinout & Package
TLV2422AIDR is housed in an 8-pin SOIC (D) package with standard dual op-amp pinout and exposed pad not present. Pin functions are electrically validated per TI SLOS199C datasheet Figure 2 (D package top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - rail-to-rail swing supports full-scale ADC input without level-shifting. |
| 2 | IN– A | Inverting input - 1 pA bias current minimizes error from high-impedance feedback networks. |
| 3 | IN+ A | Non-inverting input - common-mode range extends to VDD–, enabling ground-sensing configurations. |
| 4 | VDD– / GND | Negative supply or ground reference - shared return for both amplifiers; no separate ground pins. |
| 5 | IN+ B | Non-inverting input of second amplifier - identical specs enable matched dual-channel signal paths. |
| 6 | IN– B | Inverting input of second amplifier - supports independent differential or single-ended configurations. |
| 7 | OUT B | Second amplifier output - enables dual-stage filtering, I/V conversion + buffering in one package. |
| 8 | VDD+ | Positive supply - accepts up to 10 V; internal protection limits absolute max to 12 V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 20 mV of VDD+ and VDD– at 100 µA load - maximizes usable dynamic range in low-voltage ADC interfaces. |
| No phase inversion | Stable output polarity even when common-mode input reaches supply rails - prevents latch-up in active filters and comparators. |
| Micropower operation | 100–150 µA per channel at 25°C - reduces thermal drift and enables >10-year battery life in IoT endpoint nodes. |
| High input impedance | 10¹² Ω differential and common-mode resistance - avoids loading of high-Z sensors (e.g., thermopiles, photodiodes). |
| Low input offset drift | 2 µV/°C tempco - maintains <5 mV total offset shift over full industrial temperature range. |

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 |
|---|---|---|---|
| OPA2314AIDR | Lower VIO (1.8 mV max), higher quiescent current (100 µA vs. TLV2422AIDR's 125 µA typ), wider GBW (3 MHz vs. 52 kHz). | Better for higher-speed precision apps (e.g., active filters >10 kHz); less suitable for sub-µA sleep modes. | Select OPA2314AIDR when bandwidth >100 kHz or offset <2 mV is required; TLV2422AIDR preferred for <100 µA avg current budgets. |
| MCP6022-I/SN | Higher VIO (2.5 mV max), higher noise (25 nV/√Hz), same 1 pA bias current, but only rated to 70°C ambient. | Limited to commercial-grade applications; lacks extended temperature validation for industrial deployment. | Choose MCP6022-I/SN for cost-sensitive consumer designs where –40°C operation is unnecessary; TLV2422AIDR required for full industrial temp range. |
Compared with OPA2314AIDR and MCP6022-I/SN, TLV2422AIDR uniquely balances micropower consumption (≤150 µA), industrial temperature rating (–40°C to 85°C), and rail-to-rail output drive into 600 Ω - making it optimal for long-life, wide-temperature, low-noise sensor signal chains where speed is secondary to power and precision.

FAQ
What is the maximum supply voltage for TLV2422AIDR?
The absolute maximum supply voltage for TLV2422AIDR is 12 V, as specified in the Absolute Maximum Ratings table of the SLOS199C datasheet. However, recommended operating conditions limit VDD to 2.7 V–10 V for reliable parametric performance and long-term reliability. Operation above 10 V may cause increased quiescent current or accelerated aging without guaranteeing specifications.
Does TLV2422AIDR support true rail-to-rail input?
No, TLV2422AIDR provides rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range extends from VDD– (ground) to VDD–0.8 V at 5 V supply - meaning it accepts inputs down to 0 V but not up to VDD. This design avoids the complexity and noise penalty of full rail-to-rail input stages while retaining compatibility with ground-referenced sensors.
Can TLV2422AIDR drive a 10 kΩ load with rail-to-rail output?
Yes, TLV2422AIDR guarantees rail-to-rail output swing into 10 kΩ loads at room temperature, delivering VOH ≥ 4.97 V and VOL ≤ 0.04 V with 5 V supply. Its 600-Ω drive capability ensures robust performance even under heavier loads, but for 10 kΩ, output swing remains within 20 mV of both rails - sufficient for driving most SAR and sigma-delta ADC inputs directly.
Is TLV2422AIDR qualified for automotive applications?
TLV2422AIDR itself is rated for –40°C to +85°C and carries the "I" temperature suffix, meeting industrial requirements. While not AEC-Q200 certified, it shares design lineage with the automotive-qualified TLV2422AQD (Q-temp). For non-safety-critical cabin electronics (e.g., climate sensors), TLV2422AIDR is widely deployed - but safety-critical ADAS or powertrain systems require the Q-grade variant.
How does the input offset voltage of TLV2422AIDR compare to TLV2422IDR?
TLV2422AIDR specifies a maximum input offset voltage of 950 µV at 25°C, whereas TLV2422IDR (standard grade) has a max VIO of 2.5 mV. Both share the same 2 µV/°C temperature coefficient, but the "A" grade offers tighter initial offset - critical for DC-coupled applications like strain gauge amplification where calibration overhead must be minimized.
