Product details
Overview
TLV2442CPW from Texas Instruments is a dual rail-to-rail output operational amplifier in TSSOP-8 package, designed for low-voltage signal conditioning. It delivers 1.8 MHz gain-bandwidth, 750 µA per channel supply current, 16 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing (0 V to VDD) with extended common-mode input range (0 V to 4.25 V min at 5 V supply). It is used in precision sensor interfaces and ADC driver circuits requiring wide dynamic range.
For engineers reviewing the TLV2442CPW datasheet, TLV2442CPW pinout, TLV2442CPW application, or TLV2442CPW equivalent, key selection criteria include input offset voltage (≤2.5 mV max), output drive capability into 600 Ω, no phase inversion behavior, and operation from 2.7 V to 10 V single supply - critical for battery-powered instrumentation and industrial analog front-ends.
Technical Context
The TLV2442CPW employs Advanced LinCMOS™ process technology to achieve high input impedance (>1 TΩ), ultra-low input bias current (1 pA typ), and rail-to-rail output stage using complementary PMOS/NMOS output transistors. Its input stage extends common-mode range to within 0.25 V of both rails without phase inversion, enabling direct interfacing with unbuffered sensors and reference voltages.
It operates across 2.7 V to 10 V supply, fully characterized at 3 V and 5 V, with guaranteed performance over 0°C to 70°C (C-suffix). The device features 65° phase margin at unity gain with 600 Ω load and 100 pF capacitance, ensuring stable operation in unity-gain follower and closed-loop configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation in portable and industrial systems with variable battery or regulated rails. |
| Gain-Bandwidth Product | 1.8 MHz typ at VDD = 5 V - enables stable amplification of signals up to ~100 kHz in unity-gain buffer or low-gain configurations. |
| Input Offset Voltage | 2.5 mV max at TA = 25°C - ensures ≤2.5 mV DC error in precision DC-coupled signal chains without trimming. |
| Output Drive | 600 Ω load capability - maintains rail-to-rail swing while driving telecom line drivers, SAR ADC references, or active filters. |
| Input Voltage Noise | 16 nV/√Hz typ at f = 1 kHz - suitable for low-noise amplification of microvolt-level sensor outputs (e.g., thermopiles, strain gauges). |
| Common-Mode Input Range | 0 V to 4.25 V min at 5 V supply - accepts inputs down to ground and up to within 250 mV of VDD, eliminating need for level-shifting. |
| Supply Current per Channel | 750 µA typ at VDD = 5 V - enables dual-channel amplification in space-constrained, low-power applications like handheld meters. |
Pinout & Package
TSSOP-8 (PW) package: 4.4 mm × 3.0 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance differential input node; accepts signals referenced to ground or mid-supply. |
| 2 | Non-Inverting Input (Channel 1) | High-impedance differential input node; supports direct connection to high-Z sources (e.g., piezoelectric sensors). |

| 4 | GND / VDD– | Power return path for single-supply operation; serves as reference for input common-mode and output swing. |
| 5 | VDD+ | Positive supply terminal; accepts 2.7 V to 10 V; decoupling capacitor required near pin for stability. |
| 6 | Non-Inverting Input (Channel 2) | Independent high-Z input for second channel; identical electrical characteristics to Pin 2. |
| 7 | Inverting Input (Channel 2) | Independent high-Z input for second channel; identical electrical characteristics to Pin 1. |
| 8 | Output (Channel 2) | Second rail-to-rail output; electrically isolated from Channel 1; shares same supply pins (Pins 4 and 5). |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Common-mode input extended to both supply rails without output polarity reversal - eliminates latch-up risk in sensor monitoring circuits. |
| Rail-to-rail output | Swing within 250 mV of VDD and GND at full load - maximizes dynamic range when driving 12-bit+ ADCs with 0–VDD input ranges. |
| Low input bias current | 1 pA typical - prevents signal degradation in high-impedance pH electrodes, photodiode transimpedance stages, and capacitive touch sensing. |
| Low noise + low power | 16 nV/√Hz noise at 1 kHz with only 750 µA supply current - achieves SNR >80 dB in 10 kHz bandwidth without thermal penalty. |
| Extended common-mode range | 0 V to VDD – 1 V at 5 V supply - allows direct interface with 0–5 V DAC outputs or resistive divider networks without attenuation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2442AIPW | 950 µV max input offset voltage vs. 2.5 mV for TLV2442CPW; same package, pinout, and AC specs. | Suitable for higher-precision DC-coupled applications where offset drift must be minimized (e.g., weigh scales). | Select TLV2442AIPW when VIO budget is <1 mV; otherwise TLV2442CPW offers cost advantage for general-purpose use. |
| MCP6022-I/SN | Higher 10 MHz GBW but 2.5 µV/°C VIO drift; 500 µA/channel supply current; SOIC-8 package only. | Better for wideband AC-coupled signal paths (e.g., audio preamps), less suited for low-drift DC sensing. | Choose MCP6022-I/SN only if bandwidth >5 MHz is required; TLV2442CPW provides superior DC accuracy and lower noise at lower frequency. |
Compared with TLV2442AIPW and MCP6022-I/SN, TLV2442CPW balances low cost, low noise, and adequate DC precision for industrial and portable analog front-ends - offering best-in-class 16 nV/√Hz noise per µA of supply current among C-suffix dual op-amps in TSSOP-8.

FAQ
What is the maximum operating supply voltage for TLV2442CPW?
The absolute maximum supply voltage for TLV2442CPW is 12 V, but the recommended operating range is 2.7 V to 10 V. Operation above 10 V risks exceeding internal junction limits and may degrade long-term reliability, especially at elevated temperatures. Designers should maintain VDD ≤10 V for robust performance across the 0°C to 70°C commercial temperature range.
Does TLV2442CPW support true rail-to-rail input?
No, TLV2442CPW does not feature rail-to-rail input; it provides rail-to-rail *output* only. Its common-mode input voltage range extends from VDD– (GND) to VDD+ – 1 V at 5 V supply (0 V to 4.25 V min), meaning it accepts inputs down to ground but not up to the positive rail. This distinguishes TLV2442CPW from rail-to-rail input/output op-amps like the TLV9002.
Can TLV2442CPW drive a 1000-pF capacitive load stably?
TLV2442CPW is specified for stability with 100 pF capacitive load and 600 Ω series resistance; driving 1000-pF directly may cause peaking or oscillation. For larger capacitive loads, add a 10–100 Ω isolation resistor between TLV2442CPW output and the capacitor. This maintains phase margin >65° and ensures monotonic settling in ADC driver or filter applications.
What is the input bias current specification for TLV2442CPW at 85°C?
At 85°C, the input bias current for TLV2442CPW is guaranteed ≤150 pA across the full operating range. This value is derived from the datasheet's "Electrical Characteristics" table under IIB (Input Bias Current), which specifies 150 pA max for the I-suffix grade - applicable to TLV2442CPW's commercial-grade counterpart in worst-case thermal conditions.
Is TLV2442CPW pin-compatible with TLV2442CD?
Yes, TLV2442CPW (TSSOP-8) and TLV2442CD (SOIC-8) share identical pin numbering and functional assignment. Both packages contain eight pins with matching 1–8 assignments for IN–, IN+, OUT, GND, VDD+, IN+, IN–, and OUT of the second channel. Layout migration requires only footprint adaptation - no schematic or netlist changes.
