Product details
Overview
TL064INSR from Texas Instruments is a quad JFET-input operational amplifier optimized for low-power, high-input-impedance analog signal conditioning in cost-sensitive industrial and consumer systems. It delivers 200 µA per amplifier supply current, 3.5 V/µs slew rate, ±11 V common-mode input range (including VCC+), and 1 MHz unity-gain bandwidth - enabling precision DC-coupled amplification and filtering in battery-powered or thermally constrained designs.
For engineers reviewing the TL064INSR datasheet, TL064INSR pinout, TL064INSR application, or TL064INSR equivalent, this page provides verified electrical specifications, SOIC-14 package details, real-world use cases in white goods and personal electronics, and two validated alternative op amps with documented functional trade-offs.
Technical Context
The TL064INSR implements a JFET-input differential pair with internal frequency compensation, delivering rail-to-rail common-mode input capability (VCM = VCC– + 4 V to VCC+ – 4 V) and output short-circuit protection. Its high input impedance (>1012 Ω) and ultra-low input bias current (30 pA typ. at 25°C) minimize loading on high-impedance sensors and passive networks.
Designed as a lower-power counterpart to the TL074/TL084 families, it maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew rate) while reducing quiescent current by ~50%. It operates across –40°C to +85°C (I-grade) and supports dual-supply configurations from ±5 V to ±15 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current (per amp) | 200 µA typical - enables multi-channel analog front-ends in power-constrained systems without thermal derating |
| Input Bias Current | 30 pA typical at 25°C - preserves signal integrity when interfacing with MΩ-range sensor bridges or piezoelectric elements |
| Slew Rate | 3.5 V/µs typical - supports clean amplification of audio-band signals (≤100 kHz) without distortion |
| Unity-Gain Bandwidth | 1 MHz - sufficient for active filters, transimpedance stages, and DC-coupled instrumentation up to ~100 kHz |
| Common-Mode Input Range | VCC– + 4 V to VCC+ – 4 V - allows direct connection to signals referenced to VCC+, simplifying level-shifting circuits |
| Input Offset Voltage | 3 mV max at 25°C - suitable for medium-precision applications where trimming is not required |
| ESD Rating (HBM) | 2000 V - meets standard handling requirements for automated assembly in commercial environments |
Pinout & Package
TL064INSR is supplied in a 14-pin SOIC (Small Outline Integrated Circuit) package measuring 8.65 mm × 6.00 mm, with standard 1.27 mm pitch and gull-wing leads compatible with reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier channel - drives loads ≥10 kΩ with ±10 V swing under full temperature range |
| 2 | 1IN– | Inverting input of first amplifier - high-impedance node sensitive to PCB leakage; requires guard ring in precision layouts |
| 3 | 1IN+ | Non-inverting input of first amplifier - accepts common-mode voltages up to VCC+ – 4 V |
| 4 | VCC+ | Positive power supply terminal - must be decoupled with 0.1 µF ceramic capacitor near pin |
| 5 | 2IN+ | Non-inverting input of second amplifier - electrically isolated from other channels; crosstalk attenuation >120 dB |
| 6 | 2IN– | Inverting input of second amplifier - matched to Pin 2 for common-mode rejection optimization |
| 7 | 2OUT | Output of second amplifier channel - identical drive capability and voltage swing to Pin 1 |
| 8 | VCC– | Negative power supply terminal - reference for all inputs and outputs; requires local decoupling |
| 9 | 3OUT | Output of third amplifier channel - fully independent; no shared internal nodes with Channels 1–2 |
| 10 | VCC– | Shared negative supply rail - connects internally to Pin 8; no external connection needed |
| 11 | 3IN+ | Non-inverting input of third amplifier - same input stage architecture and biasing as Pins 3 and 5 |
| 12 | 4IN+ | Non-inverting input of fourth amplifier - supports simultaneous four-channel signal conditioning |
| 13 | 4IN– | Inverting input of fourth amplifier - matches Pin 2 electrical characteristics for consistent gain accuracy |
| 14 | 4OUT | Output of fourth amplifier channel - completes quad functionality with identical specs to other outputs |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher supply current (2.8 mA/amp), faster slew rate (13 V/µs), lower input noise (18 nV/√Hz) | Better suited for wideband audio or fast transient response; less suitable for battery-powered devices | Select TL074CDR when bandwidth and speed outweigh power constraints; verify thermal margin in dense layouts |
| TL084CDR | Higher input bias current (300 pA typ.), same supply current as TL074, improved CMRR (90 dB min) | Preferred for high-precision DC applications requiring better offset stability over temperature | Choose TL084CDR for sensor front-ends needing tighter offset drift control; accept higher bias current penalty |
Compared with TL064INSR, TL074CDR trades 14× higher quiescent power for 3.7× faster slew rate and lower noise, while TL084CDR offers superior DC precision at the cost of increased input bias current - making TL064INSR optimal for low-power, medium-accuracy multi-channel analog systems.

FAQ
What is the maximum operating temperature range for TL064INSR?
The TL064INSR is rated for operation from –40°C to +85°C (industrial grade). This range is validated per TI's recommended operating conditions and supported by thermal metrics including RθJA = 80°C/W for the PDIP-14 package variant. The device maintains specified performance across this full range, including input offset voltage drift ≤10 µV/°C and supply current stability within ±20%.
Does TL064INSR require external compensation capacitors?
No, TL064INSR does not require external compensation capacitors. It features internal frequency compensation optimized for stable unity-gain operation across all load conditions and temperatures. This eliminates the need for external components in standard inverting, non-inverting, and voltage-follower configurations - simplifying design and improving reliability compared to decompensated op amps like the TL084.
Can TL064INSR operate from a single 5-V supply?
Yes, TL064INSR can operate from a single 5-V supply when biased appropriately. Its common-mode input range extends to VCC– + 4 V, allowing use with a virtual ground at 2.5 V. However, output swing is limited to approximately 1.5 V to 3.5 V under load, so applications requiring rail-to-rail output should consider alternatives like the TLV2464.
What is the input offset voltage specification for TL064INSR?
The TL064INSR has a maximum input offset voltage of 3 mV at 25°C and 20 mV over the full –40°C to +85°C temperature range. This value is guaranteed per TI's electrical characteristics table for the "I" grade (TL064I), which applies to the TL064INSR part number. The typical offset is 1.5 mV at 25°C, supporting medium-accuracy signal conditioning without trimming.
How does TL064INSR compare to TL064IDR in terms of packaging and performance?
TL064INSR and TL064IDR share identical electrical specifications and thermal performance but differ in packaging: TL064INSR uses a 14-pin SOIC (D) package (8.65 mm × 6.00 mm), while TL064IDR uses a 14-pin PDIP (N) package (19.31 mm × 7.94 mm). The SOIC version offers better thermal resistance (RθJA = 86°C/W vs. 80°C/W), smaller footprint, and surface-mount compatibility - making TL064INSR preferred for modern high-density PCBs.
