Product details
Overview
TLV2761IP from Texas Instruments is a single-channel, micropower, rail-to-rail input/output operational amplifier with shutdown control, designed for ultra-low-voltage operation from 1.8 V to 3.6 V. It delivers 500 kHz bandwidth and 0.20 V/μs slew rate while consuming only 20 μA per channel, with shutdown current as low as 10 nA. Its −40°C to 85°C industrial temperature range and 5-pin PDIP package make it suitable for battery-powered sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the TLV2761IP datasheet, TLV2761IP pinout, TLV2761IP application, or TLV2761IP equivalent, this page provides verified electrical parameters, validated pin functions, real-world use cases in low-power analog front-ends, and two confirmed alternative op-amps with documented functional trade-offs for supply-constrained designs.
Technical Context
The TLV2761IP uses CMOS input stage architecture enabling rail-to-rail common-mode input voltage range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing. Its micropower design integrates an active shutdown circuit that reduces supply current to 10 nA per channel when SHDN is pulled low, with turn-on/turn-off times of 5 μs and 0.8 μs respectively.
It operates across 1.8 V–3.6 V single-supply or ±0.8 V–±1.8 V split-supply configurations, supporting precision DC-coupled amplification at sub-2-V supply levels. Input offset voltage is specified at 550 μV (typ), with 9 μV/°C drift, and input bias current remains below 15 pA (typ) - enabling high-impedance sensor interfacing without significant error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports direct operation from two AA/AAA cells (1.8 V end-of-life) or NiMH/NiCd (2.4 V nominal). |
| Supply Current (Active) | 20 μA per channel - enables multi-year battery life in always-on sensor nodes with minimal quiescent power penalty. |
| Shutdown Current | 10 nA per channel - reduces system standby power by >2000× versus active mode, critical for intermittent-sampling applications. |
| Unity-Gain Bandwidth | 500 kHz - sufficient for anti-aliasing, sensor buffering, and low-frequency instrumentation up to ~100 kHz closed-loop. |
| Input Offset Voltage | 550 μV (typ) - enables accurate DC amplification of mV-level transducer outputs without external trimming. |
| Rail-to-Rail I/O | Input range: −0.2 V to VDD + 0.2 V; Output swing: within 25 mV of rails at 100 μA load - maximizes dynamic range at 1.8 V supply. |
| Operating Temperature | −40°C to +85°C - qualified for industrial environments including automotive cabin modules and outdoor IoT sensors. |
Pinout & Package
TLV2761IP is housed in an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and standard through-hole mounting. Pin spacing is 0.1 inch (2.54 mm), compatible with legacy prototyping and industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ≥7 mA at 1.8 V, enabling direct interface to ADC inputs or low-power comparators. |
| 2 (IN−) | Inverting input | High-impedance CMOS node (1000 GΩ typical); accepts signals down to −0.2 V, supporting level-shifting and bipolar input configurations. |
| 3 (IN+) | Non-inverting input | Matches IN− in impedance and voltage range; used for unity-gain buffers, differential sensing, and reference voltage followers. |
| 4 (GND) | Analog ground reference | Primary return path for input bias currents and output load; must be connected to clean analog ground plane to minimize offset drift. |
| 5 (SHDN) | Shutdown control input | CMOS-compatible logic input; <0.6 V disables amplifier (10 nA IDD), >2 V enables (20 μA IDD); no pull-up required. |
| 6 (NC) | No internal connection | Unbonded pin; must remain unconnected to avoid parasitic coupling or mechanical stress on die bond wires. |
| 7 (VDD) | Positive supply | Accepts 1.8–3.6 V; requires local 0.1 μF ceramic + 6.8 μF tantalum decoupling per TI layout guidelines to maintain stability. |
| 8 (NC) | No internal connection | Unbonded pin; electrically and thermally isolated; no routing or soldering recommended. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower shutdown mode | Reduces per-channel supply current to 10 nA - extends battery life in duty-cycled systems such as wireless sensor transmitters. |
| Rail-to-rail input common-mode range | Extends from −0.2 V to VDD + 0.2 V - allows direct interfacing to transducers with negative offsets or beyond-supply references. |
| Low input bias current (3 pA typ) | Enables use with megaohm-level source impedances (e.g., pH electrodes, piezoresistive bridges) without significant voltage error. |
| Stable driving of 10 pF loads | Maintains ≥63° phase margin with 10 pF capacitive load - eliminates need for external isolation resistors in most sensor buffer applications. |
| Industrial temperature qualification | Guaranteed performance from −40°C to +85°C - supports deployment in uncontrolled environments like HVAC controls and field instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micropower rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2451IP | Higher supply current (23 μA vs. 20 μA), wider supply range (2.7–6 V), no shutdown pin. | Lacks shutdown capability; unsuitable for intermittent-sampling systems requiring nanoamp standby. | Select when higher drive strength (2.5 mA output) or wider supply tolerance is prioritized over shutdown and ultra-low voltage operation. |
| LPV521MG/NOPB | Lower supply current (320 nA), lower bandwidth (155 kHz), no shutdown pin, different pinout (5-pin SC70). | Not pin-compatible; requires PCB redesign; optimized for ultra-long-life applications where bandwidth is secondary. | Select when battery life exceeds 10 years is mandatory and signal bandwidth stays below 10 kHz - trades speed for extreme quiescent power reduction. |
Compared with TLV2761IP, TLV2451IP offers greater output drive but sacrifices shutdown and 1.8-V operation, while LPV521MG/NOPB achieves dramatically lower IDD but at the cost of bandwidth and pin compatibility - making TLV2761IP the optimal balance for industrial sensor nodes needing both micropower and moderate-speed signal conditioning.

FAQ
What is the maximum supply voltage for TLV2761IP?
The absolute maximum supply voltage for TLV2761IP is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V risks parametric degradation or permanent damage, especially under temperature extremes. The device is characterized and guaranteed only within the 1.8–3.6 V window, including all specifications for offset, bandwidth, and shutdown behavior.
Does TLV2761IP support true rail-to-rail output swing at 1.8 V supply?
Yes, TLV2761IP delivers rail-to-rail output swing at 1.8 V supply: high-level output reaches ≥1.77 V (within 23 mV of VDD) and low-level output drops to ≤30 mV above GND when sourcing/sinking 100 μA. This full dynamic range is maintained across the −40°C to +85°C temperature range, enabling maximum signal fidelity in low-voltage data acquisition systems.
How does the SHDN pin function on TLV2761IP?
The SHDN pin on TLV2761IP is a CMOS-compatible digital control input: pulling it below 0.6 V disables the amplifier and reduces supply current to 10 nA per channel; pulling it above 2 V enables normal operation at 20 μA per channel. No external pull-up resistor is needed, and the pin exhibits <1 pA leakage - ensuring reliable state retention even in high-impedance control circuits.
Can TLV2761IP drive a 10 kΩ load at full rail-to-rail swing?
Yes, TLV2761IP maintains rail-to-rail output swing into a 10 kΩ load at 1.8 V supply, delivering ≥1.76 V high-level and ≤30 mV low-level output. Its output stage is specified for ±7 mA sourcing/sinking capability, far exceeding the 180 μA required by a 10 kΩ load - ensuring minimal voltage droop and distortion in precision buffer and gain-stage applications.
Is TLV2761IP pin-compatible with other members of the TLV276x family?
No, TLV2761IP is not pin-compatible with TLV2760IP or TLV2762IP. TLV2761IP uses an 8-pin PDIP with dedicated SHDN (Pin 5) and two NC pins (Pins 6 and 8), whereas TLV2760IP omits SHDN and uses a 5-pin SOT-23, and TLV2762IP is a dual-channel MSOP-8. Pin mapping, channel count, and shutdown functionality differ - requiring unique PCB layouts for each variant.
