Product details
Overview
TLV2422CPWR from Texas Instruments is a dual rail-to-rail output, micropower operational amplifier optimized for low-voltage (2.7 V to 10 V) single-supply operation. It delivers 50 µA per channel supply current, 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 ADC front-ends.
For engineers reviewing the TLV2422CPWR datasheet, TLV2422CPWR pinout, TLV2422CPWR application, or TLV2422CPWR equivalent, key selection criteria include its 0 V to 4.5 V common-mode input range (with 5-V supply), absence of phase inversion, 600-Ω output drive capability, and guaranteed performance across 0°C to 70°C ambient temperature.
Technical Context
The TLV2422CPWR uses Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and high input impedance (>10¹² Ω), making it suitable for high-impedance source amplification such as piezoelectric transducers. Its rail-to-rail output stage operates without phase inversion even when inputs reach the supply rails.
It is fully characterized at 3-V and 5-V supplies, with specified performance over extended common-mode input voltage (0 V to 4.5 V min at VDD = 5 V) and guaranteed micropower operation (100–150 µA total IDD at 25°C). The device exhibits no internal phase reversal and supports stable unity-gain operation with 62° phase margin.
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. |
| Supply Current per Channel | 50 µA - allows continuous operation in multi-year battery-powered IoT sensors and portable medical monitors. |
| Input Offset Voltage (max) | 2.5 mV - sufficient for general-purpose signal conditioning where precision <1 mV is not required. |
| Input Bias Current (typ) | 1 pA - preserves signal integrity when amplifying from >1 GΩ sources like pH electrodes or photodiodes. |
| Output Drive Capability | 600-Ω load - supports direct interfacing with telecom line drivers and legacy analog inputs without external buffers. |
| Common-Mode Input Range | 0 V to 4.5 V (min, VDD = 5 V) - accommodates ground-referenced sensors and single-supply data acquisition systems. |
| Input Voltage Noise (1 kHz) | 18 nV/√Hz - enables low-noise amplification of microvolt-level signals in ECG front-ends and strain gauge bridges. |
Pinout & Package
TSSOP-8 (PW) package: 4.4 mm × 3.0 mm, 0.65 mm pitch, surface-mount, lead-free compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pad; must be left floating or grounded per layout best practices - no routing required. |
| 2 (VDD+) | Positive supply rail | Accepts 2.7 V to 10 V; decoupling capacitor (0.1 µF) required within 2 mm for stability. |
| 3 (2OUT) | Amplifier B output | Rail-to-rail swing (0 V to VDD); capable of sourcing/sinking ±1 mA into 600-Ω loads. |
| 4 (2IN–) | Inverting input of Amplifier B | High-impedance node (10¹² Ω); matched to Pin 5 for optimal CMRR in differential configurations. |
| 5 (2IN+) | Non-inverting input of Amplifier B | Same impedance and noise characteristics as Pin 4; supports DC-coupled sensor inputs down to 0 V. |
| 6 (NC) | No internal connection | Unused pad; no electrical function - may be used for thermal relief or mechanical anchoring. |
| 7 (1OUT) | Amplifier A output | Independent rail-to-rail output; electrically isolated from Pin 3 - enables dual-channel signal paths. |
| 8 (1IN–) | Inverting input of Amplifier A | Matches Pin 4; supports feedback networks up to 10 MΩ without significant offset drift. |
| 9 (1IN+) | Non-inverting input of Amplifier A | Identical specs to Pin 5; enables simultaneous dual-sensor buffering with matched gain accuracy. |
| 10 (VDD–/GND) | Negative supply / ground reference | Single-supply operation ties this pin to system ground; return path for both amplifiers' quiescent current. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full 0 V to VDD dynamic range - eliminates level-shifting circuitry when driving SAR ADCs with 0–VDD input ranges. |
| No phase inversion | Operates linearly even when common-mode input reaches VDD or GND - prevents latch-up and distortion in sensor buffer stages. |
| Extended common-mode input range | 0 V to 4.5 V (min, 5-V supply) - supports direct connection of unipolar transducer outputs without external biasing resistors. |
| Micropower consumption | 100–150 µA total supply current - enables integration into always-on wake-on-event nodes in wireless sensor networks. |
| Low input voltage noise | 18 nV/√Hz at 1 kHz - preserves SNR in low-frequency biosignal amplification (e.g., EEG, EMG) without requiring chopper stabilization. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2422AIPWLE | Lower max input offset voltage (950 µV vs. 2.5 mV), same PW package and pinout. | Better suited for precision DC-coupled applications (e.g., weigh scale load cell amplification) requiring sub-millivolt accuracy. | Select TLV2422AIPWLE when offset-limited error budgets demand tighter initial VIO specification. |
| MCP6022-E/SN | Higher supply current (230 µA/channel), wider GBW (10 MHz), but no guaranteed rail-to-rail output swing at light loads. | Preferred for higher-speed AC-coupled signal paths (e.g., ultrasonic receiver gain blocks) where bandwidth outweighs power constraints. | Choose MCP6022-E/SN only if slew rate (>0.5 V/µs) and bandwidth requirements exceed TLV2422CPWR's 0.008 V/µs and 52 kHz GBW. |
Compared with TLV2422AIPWLE, TLV2422CPWR trades initial offset accuracy for broader temperature qualification (C-suffix rated 0°C–70°C vs. I-suffix –40°C–85°C), while MCP6022-E/SN offers speed at the cost of 4.6× higher quiescent power and reduced output voltage headroom near supply rails.

FAQ
What is the maximum operating temperature range for TLV2422CPWR?
The TLV2422CPWR is rated for operation from 0°C to 70°C ambient temperature, as indicated by its "C" temperature suffix. This range is validated per TI's recommended operating conditions and absolute maximum ratings - exceeding this range may degrade input offset voltage stability and output drive capability.
Does TLV2422CPWR support true rail-to-rail input operation?
No, TLV2422CPWR features rail-to-rail *output* swing only. Its common-mode input voltage range extends from 0 V to VDD – 0.8 V (e.g., 0 V to 4.2 V at VDD = 5 V), which exceeds standard CMOS op-amps but does not include the positive rail. Input phase inversion is avoided across this full range.
Can TLV2422CPWR drive a 10-kΩ load with rail-to-rail output swing?
Yes - TLV2422CPWR maintains rail-to-rail output swing into 10-kΩ loads at room temperature. Data sheet Figures 1 and 2 confirm VOH ≥ 4.97 V and VOL ≤ 0.04 V at VDD = 5 V with IOH/IOL ≤ 100 µA, well within 10-kΩ load current limits (±0.5 mA).
Is TLV2422CPWR pin-compatible with other TSSOP-8 dual op-amps like LMV358?
No - TLV2422CPWR has a non-standard pinout: Pins 1 and 6 are NC, and power is applied to Pins 2 (VDD+) and 10 (VDD–/GND). LMV358 uses standard dual-op-amp pinout (V–, IN–, IN+, OUT, V+, OUT, IN+, IN–). Direct replacement requires PCB redesign.
What is the typical input bias current of TLV2422CPWR at 85°C?
At 85°C, the input bias current of TLV2422CPWR remains ≤150 pA across the full temperature range, as specified in the "Full range" column of the Electrical Characteristics tables. This stability is enabled by the Advanced LinCMOS™ process and supports high-impedance sensor interfacing in warm environments.
