Product details
Overview
TLV2341IPW from Texas Instruments is a programmable low-voltage single-supply operational amplifier in TSSOP-8 package, featuring bias-select functionality enabling 17 µA / 250 µA / 1.5 mA supply current modes, rail-to-rail output swing down to GND, and common-mode input range extending below negative rail (–0.2 V at 3 V). It operates from 2 V to 8 V across –40°C to 85°C and is optimized for battery-powered sensor signal conditioning.
For engineers reviewing the TLV2341IPW datasheet, TLV2341IPW pinout, TLV2341IPW application, or TLV2341IPW equivalent, this page delivers verified electrical specs, bias-mode tradeoffs, real-world application contexts, and validated alternative options - all tied explicitly to the TLV2341IPW variant with PW packaging and left-end tape-and-reel configuration (TLV2341IPWLE).
Technical Context
The TLV2341IPW uses LinCMOS™ silicon-gate process to achieve 10¹² Ω typical input impedance, sub-picoampere input bias current (0.6 pA typ), and ESD protection rated to 2000 V (MIL-STD-883C). Its bias-select pin (Pin 5) configures internal current mirrors to set three distinct operating points - directly altering slew rate (0.02–2.1 V/µs), unity-gain bandwidth (27–790 kHz), and input noise (68–25 nV/√Hz).
Input stage supports common-mode voltage down to –0.2 V (at VDD = 3 V) and up to VDD –1 V; output swings to within 120 mV of GND and 190 mV of VDD under 1 mA load. Absolute maximum ratings include ±30 mA output current and –0.3 V to VDD +0.3 V input voltage range, with latch-up immunity designed-in per JEDEC JESD78.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 8 V - enables direct use with single-cell Li-ion (3.0–4.2 V), two-cell alkaline (2.4–3.2 V), or regulated 3.3 V/5 V rails. |
| Input Offset Voltage (max) | 10 mV over full temperature range - sets worst-case DC error in precision gain stages without trimming. |
| Supply Current (selectable) | 17 µA / 250 µA / 1.5 mA - allows dynamic power/performance scaling: ultra-low-power sensor front-end or higher-speed signal buffering. |
| Slew Rate (high-bias mode) | 2.1 V/µs at 3 V - supports >100 kHz small-signal amplification with <1% distortion in active filters or ADC drivers. |
| Input Bias Current (typ) | 0.6 pA at 25°C - permits direct interface to high-impedance sources (e.g., pH electrodes, photodiode transimpedance inputs) without significant error. |
| Common-Mode Input Range | Extends to –0.2 V below GND at 3 V - enables true single-supply operation with ground-referenced sensors and level-shifting flexibility. |
| Output Voltage Swing | Within 120 mV of GND and 190 mV of VDD at 1 mA - ensures usable dynamic range near supply rails for low-voltage ADC interfacing. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm body, 0.65 mm pitch, 1.2 mm max height, moisture sensitivity level 1 (MSL-1), lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OFFSET N1) | Offset null input 1 | Connects to external potentiometer wiper for manual input offset trimming; unused in most applications. |
| 2 (IN–) | Inverting input | Differential input node; high-impedance LinCMOS input accepts signals down to –0.2 V at 3 V supply. |
| 3 (IN+) | Non-inverting input | Differential input node; identical voltage range and impedance as IN–; used for unity-gain buffers or non-inverting amps. |
| 4 (GND) | Analog ground reference | Primary return path for input common-mode and output current; must be low-impedance connection to system ground plane. |
| 5 (BIAS SELECT) | Bias mode control | Voltage-programmable pin: GND = low-bias (17 µA), mid-rail = medium-bias (250 µA), VDD = high-bias (1.5 mA). |
| 6 (VDD) | Positive supply | Accepts 2–8 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability across bias modes. |
| 7 (OUT) | Amplifier output | Rail-to-rail capable output driving capacitive loads ≤20 pF stably; requires isolation resistor for larger CL. |
| 8 (OFFSET N2) | Offset null input 2 | Second terminal of internal offset nulling circuit; tied to OFFSET N1 via potentiometer for calibration. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable bias current | Three discrete supply current settings (17 µA / 250 µA / 1.5 mA) enable hardware-configurable tradeoff between power and AC performance. |
| Rail-to-rail output | Swings within 120 mV of GND and 190 mV of VDD at 1 mA load - maximizes dynamic range in 3.3 V or lower systems. |
| Extended common-mode input | Operates with inputs as low as –0.2 V (at 3 V supply), supporting ground-referenced sensor interfaces without level shifters. |
| Ultra-low input bias current | 0.6 pA typical at 25°C - eliminates significant voltage error when amplifying signals from >100 MΩ sources (e.g., piezoelectric sensors). |
| Integrated ESD protection | Withstands 2000 V HBM per MIL-STD-883C Method 3015.2 - reduces need for external TVS diodes in moderate-environment industrial designs. |

FAQ
What supply voltage range does the TLV2341IPW support, and is it compatible with 3.3 V systems?
TLV2341IPW operates from 2 V to 8 V across –40°C to 85°C, fully characterized at both 3 V and 5 V. It is fully compatible with standard 3.3 V systems: input common-mode range extends to –0.2 V, output swings to within 120 mV of GND and 190 mV of 3.3 V, and all AC specifications (e.g., 2.1 V/µs slew rate, 790 kHz unity-gain bandwidth) are guaranteed at 3 V. The TLV2341IPW meets all recommended operating conditions for 3.3 V rail usage.
How does the BIAS SELECT pin on TLV2341IPW configure operating modes, and what external components are required?
The BIAS SELECT pin (Pin 5) configures TLV2341IPW into three discrete bias modes: grounded = low-bias (17 µA), mid-rail = medium-bias (250 µA), or tied to VDD = high-bias (1.5 mA). For medium-bias operation in single-supply systems, a resistive divider (e.g., two 1 MΩ resistors) is required to generate VDD/2 at the pin; large-value resistors minimize current draw but require careful RC time constant consideration during power-up. No external components are needed for low- or high-bias modes.
Does TLV2341IPW support rail-to-rail input, and what is its actual common-mode input voltage range?
TLV2341IPW does not support full rail-to-rail input - its common-mode input voltage range is specified from –0.2 V to VDD –1 V at 25°C. At 3 V supply, this means –0.2 V to 2.0 V; at 5 V, –0.2 V to 4.0 V. This extended range below ground enables true single-supply operation with ground-referenced sensors, but the upper limit remains 1 V below VDD. Input voltages beyond these limits may cause phase reversal or increased offset error.
What is the maximum capacitive load the TLV2341IPW output can drive while maintaining stability?
TLV2341IPW is characterized for stable operation with ≤20 pF capacitive load in high-bias mode (Figure 92). Driving larger loads (e.g., >50 pF) risks peaking or oscillation due to reduced phase margin - especially in medium- and low-bias modes where dominant pole shifts. For loads exceeding 20 pF, a series isolation resistor (e.g., 10–100 Ω) between OUT and the capacitor is required to restore stability, as confirmed in the device's typical characteristics and application notes.
Is TLV2341IPW pin-compatible with other TSSOP-8 op-amps like the TLV27x series?
No, TLV2341IPW is not pin-compatible with TLV27x-series TSSOP-8 op-amps. While both use TSSOP-8 packages, TLV2341IPW allocates Pins 1 and 8 to offset nulling (OFFSET N1/N2) and Pin 5 to BIAS SELECT - functions absent in TLV272/TLV274. Standard op-amps place power and output on different pins; substituting TLV2341IPW into a TLV27x layout would result in incorrect biasing, missing functionality, or failure to operate. PCB redesign is required for migration.
