Product details
Overview
TLV2341IP from Texas Instruments is a programmable low-voltage LinCMOS™ operational amplifier in PDIP-8 package, designed for single-supply operation from 2 V to 8 V across –40°C to 85°C. It features bias-select functionality enabling three supply current modes (17 µA / 250 µA / 1.5 mA), rail-to-rail output swing down to GND, and 10¹² Ω typical input impedance - ideal for battery-powered sensor signal conditioning.
For engineers reviewing the TLV2341IP datasheet, TLV2341IP pinout, TLV2341IP application, or TLV2341IP equivalent, key selection considerations include its programmable bias architecture, guaranteed operation at 3 V and 5 V, input common-mode range extending below GND, and compatibility with low-noise, low-power analog front-ends in portable instrumentation and industrial monitoring systems.
Technical Context
The TLV2341IP implements a silicon-gate LinCMOS™ process enabling ultra-low input bias current (0.6 pA typ at 25°C) and high DC precision while supporting programmable performance trade-offs via the BIAS SELECT pin. Its internal architecture includes ESD protection (2000 V HBM), latch-up immunity, and offset-null capability via dedicated OFFSET N1/N2 pins.
Operation spans three distinct bias modes: low-bias (17 µA, 0.02 V/µs slew rate), medium-bias (250 µA, 0.38 V/µs), and high-bias (1.5 mA, 2.1 V/µs at 3 V). Each mode delivers verified performance across temperature (–40°C to 85°C) and supply voltage (2–8 V), with full characterization at 3 V and 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 8 V - supports direct integration into 3 V and 5 V battery-powered systems without level-shifting. |
| Input Offset Voltage (max) | 8 mV at 25°C - ensures ≤±4 mV error in unity-gain buffer configurations at room temperature. |
| Input Bias Current (typ) | 0.6 pA at 25°C - enables use with >100 MΩ source impedances without significant DC error. |
| Slew Rate (high-bias) | 2.1 V/µs at 3 V - sufficient for 10 kHz full-scale sine wave output at 10 Vpp into 10 kΩ load. |
| Common-Mode Input Range | Extends to GND and up to VDD–1 V at 25°C - allows direct sensing of signals referenced to ground in single-supply systems. |
| Output Voltage Swing | Includes negative rail (GND) - delivers true 0 V output for interfacing with ADCs or logic-level circuitry. |
| ESD Rating | 2000 V per MIL-STD-883C Method 3015.2 - provides robust handling margin during PCB assembly and field service. |
Pinout & Package
TLV2341IP is housed in an 8-pin plastic DIP (P) package with 0.3-inch body width and through-hole mounting. Pin 1 is identified by a notch or dot; pin numbering follows standard counter-clockwise orientation when viewed from top.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OFFSET N1) | Offset null input | Connects to external potentiometer wiper for manual input offset trimming; required for <1 mV precision applications. |
| 2 (IN–) | Inverting input | Differential input node; accepts signals within common-mode range (GND to VDD–1 V). |
| 3 (IN+) | Non-inverting input | Differential input node; high-impedance (10¹² Ω typ) interface to sensors or reference sources. |
| 4 (GND) | Ground reference | System ground return path; must be low-impedance to maintain PSRR (>65 dB) and noise immunity. |
| 5 (BIAS SELECT) | Bias configuration control | Voltage level (GND = low-bias, VDD/2 = medium-bias, VDD = high-bias) sets supply current and ac performance. |
| 6 (VDD) | Positive supply | Single positive rail (2–8 V); no negative supply required - simplifies power design in portable systems. |
| 7 (OUT) | Amplifier output | Capable of sourcing/sinking ±30 mA; swings to GND and up to VDD–1.2 V (at 1 mA load). |
| 8 (OFFSET N2) | Offset null output | Second terminal of internal offset nulling network; completes trim circuit with OFFSET N1. |
Key Features
| Feature | Design Value |
|---|---|
| Bias-select programmability | Three discrete operating points (17 µA / 250 µA / 1.5 mA) enable dynamic trade-off between power and bandwidth without hardware change. |
| Rail-to-rail output | Output reaches GND and delivers ≥1.75 V at VDD=3 V with –1 mA load - eliminates need for negative supply in sensor interfaces. |
| Ultra-high input impedance | 10¹² Ω typical input resistance preserves signal integrity from high-Z sources like piezoelectric sensors or pH electrodes. |
| Low input offset drift | 2.7 µV/°C max over –40°C to 85°C - maintains <0.3 mV total offset shift across industrial temperature range. |
| Integrated ESD protection | 2000 V HBM rating on all pins - reduces need for external TVS diodes in cost-sensitive consumer and industrial designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L1CP | Fixed low-power mode (10 µA), no bias-select pin; lower input impedance (10¹³ Ω typ), higher offset (10 mV max). | Lacks programmability - suitable only for static ultra-low-power cases where 2.1 V/µs slew rate is unnecessary. | Select when absolute minimum supply current (<10 µA) outweighs need for bandwidth flexibility. |
| LPV521MG/NOPB | Fixed rail-to-rail I/O, 320 nA supply current, no offset-null pins; 1.4 MHz GBW vs TLV2341IP's 790 kHz (high-bias). | No BIAS SELECT or OFFSET N1/N2 - eliminates trimming but removes fine-tuning capability for precision DC apps. | Select for modern SMT designs requiring smaller SC-70 package and guaranteed 1.4 MHz bandwidth at 320 nA. |
Compared with TLC27L1CP and LPV521MG/NOPB, TLV2341IP uniquely combines programmable bias, offset trimming capability, and proven DIP-8 reliability for legacy and repair-focused industrial applications - making it irreplaceable where configurability and long-term serviceability are mandatory.

FAQ
What supply voltage range does the TLV2341IP support?
The TLV2341IP operates from 2 V to 8 V over the full industrial temperature range (–40°C to 85°C), with full electrical characterization at both 3 V and 5 V. This makes TLV2341IP suitable for direct integration into coin-cell, Li-ion, and regulated 3.3 V/5 V systems without external regulators or level shifters.
How does the BIAS SELECT pin configure TLV2341IP performance?
The BIAS SELECT pin on TLV2341IP sets one of three operating modes: grounding selects low-bias (17 µA, 0.02 V/µs), connecting to VDD/2 selects medium-bias (250 µA, 0.38 V/µs), and tying to VDD selects high-bias (1.5 mA, 2.1 V/µs at 3 V). TLV2341IP's datasheet Table 1 quantifies resulting slew rate, noise, and bandwidth trade-offs for each mode.
Does TLV2341IP support rail-to-rail output?
Yes, TLV2341IP delivers true rail-to-rail output swing down to GND and up to VDD–1.2 V (at 1 mA load), verified across temperature and supply voltage. This eliminates the need for negative supplies in single-ended sensor interfaces and simplifies interfacing with ADCs or logic that reference GND.
Can TLV2341IP be used with high-impedance sensor sources?
Yes - TLV2341IP features 10¹² Ω typical input impedance and 0.6 pA typical input bias current at 25°C, enabling accurate amplification of signals from sources with impedances exceeding 100 MΩ, such as pH electrodes, photodiodes, and piezoelectric transducers, without significant loading error.
Is offset adjustment possible on TLV2341IP?
Yes, TLV2341IP provides dedicated OFFSET N1 and OFFSET N2 pins for external nulling using a 10 kΩ potentiometer. This allows reduction of input offset voltage to <1 mV in precision applications - a capability not found in most modern low-power op-amps and critical for TLV2341IP's use in calibrated measurement systems.
