Product details

Overview

TL064ID from STMicroelectronics is a low-power JFET-input quad operational amplifier in SO-14 package, delivering 3.5 V/µs slew rate, ±15 V input voltage range, and 200 µA supply current per amplifier. It operates across –40°C to +105°C, features high input impedance (10¹² Ω), output short-circuit protection, and is used in audio signal distribution, sensor conditioning, and precision DC amplification circuits.

For engineers reviewing the TL064ID datasheet, TL064ID pinout, TL064ID application, or TL064ID equivalent, key selection criteria include JFET-input bias current (≤200 pA), common-mode range extending to V_CC, channel separation of 120 dB, and thermal stability over industrial temperature range - all critical for low-noise analog front-ends and multi-channel instrumentation.

Technical Context

The TL064ID integrates four matched JFET-input op-amps on a single monolithic die, using high-voltage JFET and bipolar transistor co-design to achieve low offset drift (10 µV/°C) and latch-up-free operation. Its internal frequency compensation ensures unity-gain stability with 1 MHz gain-bandwidth product.

Each amplifier supports rail-to-rail common-mode input (±11.5 V min at ±15 V supply) and delivers ±27 V_PP output swing into 10 kΩ load. The device maintains 80–86 dB CMRR and 80–95 dB SVRR across temperature, enabling robust performance in noisy industrial environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply current	200 µA per amplifier - enables battery-powered or energy-constrained systems with four independent gain stages
Slew rate	3.5 V/µs - supports audio-frequency signal integrity up to ~100 kHz without distortion in unity-gain follower configurations
Input bias current	≤200 pA (max, TL064I grade) - preserves accuracy in high-impedance sensor interfaces (e.g., piezoelectric or pH electrodes)
Input resistance	10¹² Ω - minimizes loading error when buffering high-Z sources like crystal oscillators or photodiode transimpedance nodes
Channel separation	120 dB - prevents crosstalk between adjacent channels in multi-channel data acquisition or audio mixing applications
Common-mode range	±11.5 V (min) at ±15 V supply - allows direct interfacing with bipolar sensors or DAC outputs without level-shifting circuitry
Output short-circuit duration	Infinite - permits safe operation in fault-prone industrial I/O modules without external current-limiting components

Pinout & Package

TL064ID is supplied in SO-14 (Small Outline, 14-pin) plastic micropackage, 8.55 mm × 5.8 mm body, 1.27 mm pitch, surface-mount compatible.

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Amplifier A)	High-impedance differential node for negative feedback configuration; accepts signals down to –12 V with ±15 V supplies
2	Non-inverting Input (Amplifier A)	Reference point for single-ended or differential sensing; common-mode range extends to V_CC+
3	Output (Amplifier A)	Capable of ±27 V_PP swing into 10 kΩ; internally short-circuit protected
4	V_CC– (Negative Supply)	Ground reference for dual-supply operation; must be connected to system negative rail or GND in single-supply configs
5	Inverting Input (Amplifier B)	Independent input stage; electrically isolated from other amplifiers except shared supply rails
6	Non-inverting Input (Amplifier B)	Matches Pin 2 characteristics; supports identical biasing and signal routing practices
7	Output (Amplifier B)	Same AC/DC specs as Pin 3; channel separation >120 dB prevents interaction with Amplifier A
8	V_CC+ (Positive Supply)	Accepts 6–36 V total supply span (±3 V to ±18 V); powers all four amplifiers simultaneously
9	Inverting Input (Amplifier C)	Third independent channel; pin-compatible with Pins 1 and 5 for layout reuse
10	Non-inverting Input (Amplifier C)	Supports same input voltage range and bias current specs as other non-inverting inputs
11	Output (Amplifier C)	Delivers full output swing with <0.2 µs rise time; suitable for driving 10 kΩ loads directly
12	Inverting Input (Amplifier D)	Fourth channel input; matches electrical behavior of Pins 1/5/9 under all operating conditions
13	Non-inverting Input (Amplifier D)	Enables four-channel parallel processing without inter-channel gain mismatch beyond 3 mV V_io max
14	Output (Amplifier D)	Final output stage; shares thermal resistance (R_thjc = 31 °C/W) with other channels in SO-14 package

Key Features

Feature	Design Value
Low power consumption	200 µA per amplifier enables 4-channel analog signal processing in sub-1 mA total supply budget
JFET input stage	10¹² Ω input resistance and ≤200 pA bias current preserve signal fidelity in high-impedance sensor front-ends
Wide common-mode range	Extends to V_CC+ and down to –12 V, eliminating need for input level shifters in bipolar signal chains
Output short-circuit protection	Allows indefinite shorting to either rail or ground without damage - critical for industrial I/O protection
Latch-up free operation	Guaranteed immunity to parasitic SCR triggering under overvoltage or ESD stress per HBM 900 V rating

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad JFET-input op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TL074CD	Higher slew rate (13 V/µs), lower noise (18 nV/√Hz), but higher supply current (2.5 mA per amp)	Better suited for wideband audio or fast-settling data acquisition where power is not constrained	Select TL074CD only if bandwidth >10 MHz or noise <20 nV/√Hz is required; avoid in battery-powered designs
RC4136N	Wider supply range (±4 V to ±18 V), lower input offset (2 mV typ), but no guaranteed industrial temp grade	Preferred for commercial-grade instrumentation where cost sensitivity outweighs extended temperature needs	Choose RC4136N for cost-driven consumer electronics; TL064ID remains optimal for –40°C to +105°C reliability-critical use

Compared with TL074CD and RC4136N, TL064ID uniquely balances ultra-low quiescent current (200 µA), industrial temperature rating, and JFET-input integrity - making it the only choice for long-life, low-power, multi-channel analog systems deployed in harsh environments.

FAQ

What is the maximum supply voltage for TL064ID?

The absolute maximum supply voltage is ±18 V (36 V total), but recommended operating range is ±3 V to ±18 V. Operation at ±18 V requires derating power dissipation per the 680 mW limit and thermal resistance (R_thja = 105 °C/W for SO-14). Exceeding ±18 V risks permanent damage to the JFET input stage.

Does TL064ID support single-supply operation?

Yes - TL064ID can operate from a single +12 V supply with V_CC– tied to ground, provided input signals remain within the common-mode range (0 V to +9.5 V typical). Output swing will be limited to ~0.5 V to ~11.5 V into 10 kΩ, and level-shifting or rail-splitting may be needed for true DC-coupled bipolar signal handling.

How does TL064ID compare to TL084 in terms of noise performance?

TL064ID specifies 42 nV/√Hz input noise at 1 kHz, while TL084 is rated at 18 nV/√Hz. This 2.3× higher noise stems from TL064's optimized low-power JFET design; it trades noise floor for 10× lower supply current (200 µA vs. 2.5 mA). Use TL064ID where power efficiency dominates; choose TL084 only when low-noise wideband amplification is essential.

Is TL064ID pin-compatible with other quad op-amps in SO-14 package?

TL064ID uses standard SO-14 pinout per JEDEC MS-012, matching TL074, TL084, and RC4136. However, electrical differences - especially supply current, slew rate, and input bias - mean direct substitution requires validation of loop stability, settling time, and thermal margin. No functional or timing compatibility is guaranteed without circuit-level requalification.
