Product details
Overview
TLV2422CPW 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 full dynamic range in battery-powered sensor signal conditioning and ADC interface circuits.
For engineers reviewing the TLV2422CPW datasheet, TLV2422CPW pinout, TLV2422CPW application, or TLV2422CPW equivalent, key selection criteria include its 950 µV max input offset voltage (TLV2422A variant), 0.008 V/µs slew rate, 52 kHz gain-bandwidth product at 5 V, extended common-mode input range (0 V to 4.5 V), and TSSOP-8 package compatibility with space-constrained analog front-ends.
Technical Context
The TLV2422CPW uses Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and high input impedance (>1 TΩ), 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 phase inversion - critical for precision single-supply systems.
It operates across 2.7 V to 10 V supply rails with guaranteed performance at 3 V and 5 V, and features no phase inversion when common-mode inputs reach either supply rail. The device is fully characterized over 0°C to 70°C (C-suffix) and exhibits 70 dB minimum CMRR and 80 dB minimum PSRR across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports direct integration into 3.3 V and 5 V systems without level-shifting. |
| Supply Current per Channel | 100–150 µA (typ 100 µA at 25°C) - enables multi-year battery life in portable monitoring devices. |
| Input Offset Voltage (max) | 2000 µV at 25°C (TLV2422C) - defines DC accuracy limit in precision amplification stages. |
| Input Bias Current (typ) | 1 pA - minimizes voltage error across high-value feedback or sensor source impedances. |
| Output Swing | Rail-to-rail - delivers full 0 V to VDD output range, maximizing ADC utilization in single-supply data acquisition. |
| Common-Mode Input Range | 0 V to VDD – 0.8 V - allows input signals to extend to ground, simplifying sensor biasing in low-voltage designs. |
| Gain-Bandwidth Product | 52 kHz at VDD = 5 V - sets usable bandwidth for low-frequency signal conditioning (e.g., ECG, temperature, strain). |
Pinout & Package
TSSOP-8 (PW) package: 4.4 mm × 3.0 mm, 0.65 mm pitch, thin-profile surface-mount. Pin 1 marked by dot; exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or grounded per layout best practices. |
| 2 | VDD+ | Positive supply rail - decoupling capacitor (0.1 µF) required within 2 mm for stability. |
| 3 | 2OUT | Output of second op-amp - drives 600-Ω loads with rail-to-rail swing up to ±50 mA short-circuit current. |
| 4 | 2IN– | Inverting input of second op-amp - high-impedance node (1 TΩ); sensitive to PCB leakage and guarding. |
| 5 | 2IN+ | Non-inverting input of second op-amp - matched to 2IN– for optimal CMRR; requires symmetrical trace routing. |
| 6 | NC | No internal connection - must be left floating or grounded per layout best practices. |
| 7 | 1OUT | Output of first op-amp - independently buffered; shares same rail-to-rail output architecture as Pin 3. |
| 8 | 1IN– | Inverting input of first op-amp - paired with Pin 9 (1IN+) for differential gain configuration. |
| 9 | 1IN+ | Non-inverting input of first op-amp - used with Pin 8 for unity-gain buffer or instrumentation amplifier front-end. |
| 10 | VDD–/GND | Negative supply or ground reference - low-impedance return path essential for noise immunity and PSRR performance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Enables full-scale signal swing into ADCs and low-voltage DACs without headroom loss. |
| No phase inversion | Prevents catastrophic output latch-up when common-mode input exceeds supply rails - eliminates need for input clamping. |
| 1 pA input bias current | Reduces offset error in high-Z sensor interfaces (e.g., photodiode transimpedance, pH probe buffers). |
| 18 nV/√Hz input voltage noise | Supports clean amplification of microvolt-level signals (e.g., thermocouples, bio-potentials) at 1 kHz. |
| Extended common-mode range | Accepts inputs down to ground on single supply - simplifies biasing of AC-coupled sensors and bridge circuits. |
Applications
| Portable Medical Sensors | Industrial Process Monitoring |

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 |
|---|---|---|---|
| MCP6022-I/P | Higher supply current (180 µA/ch), wider GBW (1 MHz), but only 2.7 V min supply; no guaranteed rail-to-rail output at light loads. | Better for higher-speed sensor interfaces (e.g., ultrasonic TOF), less suitable for <50 µA battery budget. | Select MCP6022-I/P when bandwidth >100 kHz is required and supply current margin exists. |
| OPA2333AIDR | Zero-drift architecture; 2 µV max VIO, 0.1 µV/°C drift, but 17 µA/ch supply current and 350 kHz GBW. | Superior DC precision for long-term calibration stability; trades micropower for offset performance. | Select OPA2333AIDR when <5 µV total input offset error over temperature is mandatory, and 17 µA/ch is acceptable. |
Compared with MCP6022-I/P and OPA2333AIDR, TLV2422CPW uniquely balances ultra-low quiescent current (100 µA total), rail-to-rail output, and robust 0–4.5 V input range - making it optimal for cost-sensitive, battery-limited, single-supply industrial and medical sensing where moderate bandwidth suffices.

FAQ
What is the maximum operating temperature range for TLV2422CPW?
The TLV2422CPW is rated for 0°C to 70°C ambient operation (C-suffix grade). It is not qualified for automotive or extended industrial temperature ranges - those require TLV2422I (–40°C to 85°C) or TLV2422AQ (–40°C to 125°C) variants. Always verify thermal derating using the 4.2 mW/°C dissipation factor for the PW package.
Does TLV2422CPW support true rail-to-rail input?
No, TLV2422CPW provides rail-to-rail *output* only. Its common-mode input voltage range extends from VDD– (ground) to VDD+ – 0.8 V - meaning it accepts inputs down to ground but not up to the positive rail. For full rail-to-rail input capability, consider TI's TLV27x or OPA333 families.
Can TLV2422CPW drive a 600-Ω load effectively?
Yes, TLV2422CPW is explicitly specified to drive 600-Ω loads with rail-to-rail output swing. At 5 V supply and 25°C, VOH ≥ 4.75 V and VOL ≤ 0.15 V under 500 µA load - meeting telecom and legacy analog interface requirements. Output current capability is ±50 mA short-circuit limited.
Is TLV2422CPW pin-compatible with other TSSOP-8 dual op-amps?
No - TLV2422CPW has two NC pins (Pins 1 and 6) and non-standard pinout (e.g., VDD+ on Pin 2, GND on Pin 10). It is not pin-compatible with industry-standard dual op-amps like LMV358 or MCP6022. PCB layout must follow the exact PW-package pin mapping shown in the datasheet Figure 2.
What is the typical input voltage noise of TLV2422CPW at 1 kHz?
The typical input voltage noise of TLV2422CPW is 18 nV/√Hz at 1 kHz and 5 V supply, as confirmed in Section 12 of the SLOS199C datasheet. This value increases to 23 nV/√Hz at 3 V supply. Noise performance remains stable across temperature and load conditions within recommended operating ranges.
