Product details
Overview
TLE2061BIP from Texas Instruments is a precision JFET-input operational amplifier optimized for low-power, high-output-drive applications. It delivers 2 MHz unity-gain bandwidth, 290 µA typical supply current per channel, and on-chip zener-trimmed offset voltage (max 1.5 mV at 25°C). Designed for ±5 V to ±18 V dual-supply operation, it drives 100-Ω loads and supports dc-coupled sensor interfaces and modem transformer drivers.
For engineers reviewing the TLE2061BIP datasheet, TLE2061BIP pinout, TLE2061BIP application, or TLE2061BIP equivalent, key selection criteria include its BiFET input stage (10¹² Ω input resistance), low 1.5 mV max VIO over −40°C to 85°C, 2.2 V/µs min slew rate at ±5 V, 65 dB min CMRR, and compatibility with single-supply biasing via virtual ground circuits like TLE2426.
Technical Context
The TLE2061BIP uses Texas Instruments' Excalibur BiFET process to double the bandwidth of TL06x/TL03x families without increasing power consumption. Its JFET input stage provides ultra-low input bias current (≤3 pA typ) and high input impedance, while bipolar output circuitry enables ±80 mA output drive into low-impedance loads.
It features on-chip offset voltage trimming for precision dc performance, specified across −40°C to 85°C (I-suffix grade), and supports stable operation into 100-Ω loads at ±5 V supplies - a capability uncommon among low-power op amps of its era.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 1.3 MHz at ±5 V, RL = 100 Ω - enables stable closed-loop gain ≥1 with adequate phase margin (75°) |
| Supply current per channel | 290 µA typ at ±5 V - allows battery-powered or energy-constrained systems to maintain bandwidth without excessive quiescent draw |
| Input offset voltage | Max 1.5 mV at 25°C, 3.9 mV over −40°C to 85°C - supports precision dc-coupled signal conditioning without external nulling |
| Output drive capability | ±2.5 V swing into 100 Ω at ±5 V - directly drives transformers, cables, or low-Z analog front-ends without buffer stages |
| Input bias current | 3 pA typ, ≤4 nA max over temperature - preserves signal integrity in high-impedance sensor nodes (e.g., piezoelectric, pH electrodes) |
| Common-mode input range | −1.6 V to +4 V at ±5 V supply - requires external dc biasing for single-supply use but supports rail-to-rail input when referenced to mid-supply |
| CMRR | 65 dB min over full temperature range - rejects supply noise and common-mode interference in noisy industrial environments |
Pinout & Package
Package: 8-pin plastic DIP (P package), through-hole mounting, 0.3-inch wide body, compatible with standard IC sockets and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Trim connection for internal offset voltage adjustment; tied to external potentiometer for fine calibration (not required for standard operation) |
| 2 | IN− | Inverting input terminal; high-impedance JFET node (10¹² Ω) for feedback network attachment |
| 3 | IN+ | Non-inverting input terminal; matched to IN− for optimal common-mode rejection |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally to minimize noise coupling into input stage |
| 5 | NC | No internal connection; electrically isolated - no routing or grounding required |
| 6 | VCC+ | Positive supply rail connection; symmetric dual-supply operation required for full specification compliance |
| 7 | OUT | Amplified output node; capable of sourcing/sinking ±80 mA, driving capacitive loads up to 100 pF stably |
| 8 | OFFSET N2 | Second trim connection; used with OFFSET N1 for dual-point calibration in high-precision applications |
Key Features
| Feature | Design Value |
|---|---|
| BiFET input architecture | Combines JFET input (10¹² Ω Rin, 1 pA IIB) with bipolar output stage for high Zin and ±80 mA IOUT - ideal for interfacing high-Z sensors without loading |
| Zener-trimmed offset voltage | 1.5 mV max at 25°C (TLE2061B grade) - eliminates need for external nulling in dc-coupled instrumentation amplifiers |
| Low-noise operation | 43 nV/√Hz input voltage noise at 1 kHz - suitable for audio preamps and low-level signal amplification where SNR matters |
| High-output-drive capability | 2.5 V swing into 100 Ω at ±5 V - enables direct driving of 1:1 audio transformers or 50-Ω coaxial lines without external buffers |
| Wide supply range | ±3.5 V to ±18 V operation - supports legacy ±5 V, ±12 V, and ±15 V systems without redesign |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | Higher supply current (2.5 mA vs. 290 µA), higher VIO (10 mV max), no offset trim pins | Lacks precision dc performance and low-power suitability; better for general-purpose AC-coupled use | Select TL071CP only when higher speed (4 MHz GBW) outweighs power and offset requirements |
| TLC27L1CP | CMOS input (50 fA IIB), lower bandwidth (850 kHz), higher VIO (5 mV max), no trim pins | Better for ultra-low-power, high-Z DC applications but insufficient output drive for transformer loads | Choose TLC27L1CP for micropower sensor nodes where 100-Ω drive is unnecessary |
Compared with TL071CP and TLC27L1CP, the TLE2061BIP uniquely balances low power (290 µA), precision (1.5 mV VIO), and high output drive (±2.5 V into 100 Ω) - making it irreplaceable in space-constrained, battery-operated, or transformer-coupled analog systems requiring both accuracy and drive strength.

FAQ
What is the maximum operating temperature range for the TLE2061BIP?
The TLE2061BIP is rated for operation from −40°C to +85°C (I-suffix grade). This extended industrial temperature range ensures reliable performance in factory automation, outdoor telecom equipment, and automotive under-hood applications where ambient temperatures exceed commercial limits. The device maintains all key specifications - including 1.5 mV max input offset voltage and 290 µA supply current - across this full range.
Does the TLE2061BIP support single-supply operation?
The TLE2061BIP is designed for dual-supply operation but can be used in single-supply configurations with proper dc biasing. Its common-mode input range at ±5 V is −1.6 V to +4 V, so a virtual ground (e.g., using TI's TLE2426) must be established at mid-supply to keep inputs within spec. Output swing remains asymmetric without rail-splitting, limiting dynamic range unless input/output coupling capacitors are added.
What is the purpose of the OFFSET N1 and OFFSET N2 pins on the TLE2061BIP?
The OFFSET N1 and OFFSET N2 pins on the TLE2061BIP provide access to the internal zener-trimmed offset voltage network. Connecting a 10-kΩ potentiometer between them and adjusting its wiper to VCC− allows fine-tuning of input offset voltage down to <100 µV - critical for high-accuracy dc-coupled applications like precision weigh scales or medical instrumentation where factory-trimmed 1.5 mV VIO is insufficient.
How does the TLE2061BIP compare to the TL061 in terms of bandwidth and power consumption?
The TLE2061BIP delivers 2 MHz unity-gain bandwidth - exactly double the 1 MHz of the TL061 - while consuming only 290 µA supply current versus TL061's 250 µA. This 100% bandwidth increase with negligible power penalty makes the TLE2061BIP a drop-in upgrade for TL061-based designs needing faster settling, wider signal bandwidth, or improved transient response without redesigning power delivery.
Can the TLE2061BIP drive a 50-Ω coaxial cable directly?
The TLE2061BIP is specified to drive 100-Ω loads with ±2.5 V swing at ±5 V supplies; driving a 50-Ω load exceeds its safe operating area and risks thermal overstress or reduced linearity. For 50-Ω systems, use an external series resistor (e.g., 50 Ω) to isolate the op amp, or select a dedicated line driver like the THS3091. Direct 50-Ω termination is not recommended per TI's absolute maximum ratings and thermal derating guidelines for the TLE2061BIP.
