Product details
Overview
TLV2771CDR from Texas Instruments is a single-channel CMOS rail-to-rail output operational amplifier optimized for low-voltage, low-power precision signal conditioning. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, 1 mA supply current per channel, and operates from 2.5 V to 5.5 V - enabling high-fidelity analog front-end design in portable medical sensors and battery-powered data acquisition systems.
For engineers reviewing the TLV2771CDR datasheet, TLV2771CDR pinout, TLV2771CDR application, or TLV2771CDR equivalent, this page provides verified electrical specifications, SOT-23-5 package terminal mapping, real-world use cases in ADC driving and telecom line drivers, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV2771CDR employs a CMOS input stage with 2 pA input bias current and 17 nV/√Hz input noise voltage at 10 kHz, supporting high-impedance sensor interfacing. Its rail-to-rail output swing (within 100 mV of rails at 1.3 mA load) and 0.005% THD+N into 600 Ω enable direct connection to SAR ADC reference inputs and audio codec line drivers without external level-shifting.
Characterized across −40°C to 125°C and specified at both 2.7 V and 5 V supplies, the device features micropower shutdown mode (<1 µA), making it suitable for duty-cycled instrumentation where quiescent current must be minimized between measurement cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 10.5 V/µs typ - enables accurate reproduction of fast transient signals up to ~1.7 MHz full-power bandwidth into 10 kΩ load. |
| Gain-Bandwidth Product | 5.1 MHz typ - supports stable unity-gain and inverting configurations with ≥46° phase margin into 600 Ω + 100 pF. |
| Input Offset Voltage | 360 µV max at 25°C - ensures ≤0.014% gain error in 2.5 V full-scale 12-bit ADC driver applications. |
| Supply Current | 1 mA per channel typ - allows 10+ channels on a 10 mA LDO in portable multichannel sensor nodes. |
| Input Bias Current | 2 pA typ - minimizes voltage error across >1 MΩ source impedances (e.g., pH electrodes, piezoelectric sensors). |
| THD+N | 0.005% at 1 kHz, RL = 600 Ω - meets telecom line-driver spectral purity requirements per ITU-T G.712. |
| Operating Voltage | 2.5 V to 5.5 V - compatible with Li-ion (3.0–4.2 V), 3.3 V logic, and dual-supply ±2.5 V systems via single-rail configuration. |
Pinout & Package
TLV2771CDR is supplied in a 5-pin SOT-23 (DBV) package with exposed pad (thermal performance optimized for PCB copper area). Pin 1 is marked by a molded dot or beveled edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Rail-to-rail output capable of sourcing/sinking ±2.2 mA while maintaining <100 mV headroom to rails. |
| 2 | IN− | Inverting input - high-impedance CMOS node (10¹² Ω) with 2 pA bias current for minimal loading of feedback networks. |
| 3 | IN+ | Non-inverting input - matched to IN− for optimal common-mode rejection (CMRR ≥60 dB over 0–1.5 V range). |
| 4 | GND | Analog ground reference - must be connected to low-impedance system ground plane to maintain PSRR (≥70 dB) and noise immunity. |
| 5 | VDD | Positive supply - accepts 2.5–5.5 V; internal ESD protection clamps to GND and VDD limit absolute max to ±0.3 V beyond rails. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 100 mV of VDD and GND at 1.3 mA load - eliminates need for level-shifting when interfacing with 3.3 V ADC references. |
| Low distortion into 600 Ω | 0.005% THD+N at 1 kHz - satisfies voice-grade line driver specs for VoIP and PBX interface circuits. |
| Micropower shutdown | IDD(SHDN) < 1 µA - reduces total system standby power by >99.9% vs active mode in wake-on-event sensor nodes. |
| Extended temperature range | Specified from −40°C to 125°C - qualified for under-hood automotive and industrial control cabinet deployments. |
| Low input noise density | 17 nV/√Hz at 10 kHz - preserves SNR in amplification stages preceding 16-bit delta-sigma ADCs. |
Applications
| ADC Analog Front-End | Portable Medical Sensor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture (0.02 µV/°C drift), lower offset (10 µV max), higher supply current (17 µA), no shutdown. | Better DC stability in temperature-varying environments; unsuitable for ultra-low-power shutdown modes. | Select OPA333AIDBVR when long-term offset drift dominates error budget over quiescent power. |
| MCP6001T-E/OT | Lower bandwidth (1 MHz), higher offset (1.5 mV max), lower supply current (100 µA), rail-to-rail I/O, no shutdown. | Cost-optimized for non-critical DC-coupled buffers; insufficient slew rate for audio or fast-settling ADC drivers. | Select MCP6001T-E/OT for space-constrained, cost-sensitive applications where 10.5 V/µs slew rate is not required. |
Compared with TLV2771CDR, OPA333AIDBVR trades 16× higher quiescent current for 36× lower offset drift, while MCP6001T-E/OT reduces cost and size but sacrifices 5× bandwidth and 4× slew rate - making TLV2771CDR the balanced choice for battery-powered precision signal chains requiring both speed and efficiency.

FAQ
What is the maximum operating temperature range for TLV2771CDR?
The TLV2771CDR is rated for operation from −40°C to 125°C, meeting industrial and automotive under-hood requirements. This rating is confirmed in the "recommended operating conditions" table of the official SLOS209G datasheet, and applies specifically to the CDR (SOT-23-5) variant with C-suffix temperature grade.
Does TLV2771CDR include a shutdown function?
No, TLV2771CDR does not include a shutdown pin or function. The TLV2771 family member with shutdown is TLV2770 (dual-channel, 8-pin SOIC/SOT-23), not TLV2771. The TLV2771CDR datasheet explicitly lists "No" under shutdown capability in the FAMILY PACKAGE TABLE and omits SHDN pin in all TLV2771 pinouts.
What is the typical input bias current of TLV2771CDR?
The typical input bias current of TLV2771CDR is 2 pA at 25°C, as specified in the "electrical characteristics" tables for VDD = 2.7 V and VDD = 5 V in the SLOS209G datasheet. This value remains stable across the full −40°C to 125°C operating range, supporting high-impedance sensor interfaces.
Can TLV2771CDR drive a 600 Ω load with low distortion?
Yes, TLV2771CDR delivers 0.005% THD+N into a 600 Ω load at 1 kHz with AV = 1, as measured per standard test conditions in the SLOS209G datasheet (page 9, operating characteristics at VDD = 5 V). This performance meets ITU-T G.712 voice-grade line driver requirements.
Is TLV2771CDR pin-compatible with other SOT-23-5 op-amps like MCP6001?
No, TLV2771CDR is not pin-compatible with MCP6001T-E/OT. While both use SOT-23-5 packages, TLV2771CDR assigns Pin 1 to OUT, Pin 2 to IN−, Pin 3 to IN+, Pin 4 to GND, and Pin 5 to VDD - whereas MCP6001 uses Pin 1 = NC, Pin 2 = IN−, Pin 3 = IN+, Pin 4 = VDD, Pin 5 = OUT. Swapping them causes functional failure.
