Product details
Overview
TL064BIDT from STMicroelectronics is a low-power JFET-input quad operational amplifier designed for precision analog signal conditioning in space-constrained industrial and test equipment. It delivers 200 µA supply current per amplifier, ±11.5 V input common-mode range (with ±15 V supplies), 3.5 V/µs slew rate, 1 MHz gain-bandwidth product, and 10¹² Ω input resistance - enabling high-impedance sensor interfacing and battery-powered instrumentation.
For engineers reviewing the TL064BIDT datasheet, TL064BIDT pinout, TL064BIDT application, or TL064BIDT equivalent, key selection criteria include its JFET-input bias current (≤7 pA typ.), low offset voltage drift (10 µV/°C), rail-to-rail output swing capability (±13.5 V into 10 kΩ), and SO-14 package compatibility with automated SMT assembly lines.
Technical Context
The TL064BIDT integrates four matched JFET-input op-amp cells on a single monolithic die, each featuring internal frequency compensation, output short-circuit protection, and latch-up-free operation. Its high input impedance and low input bias current stem from the JFET differential pair architecture, not CMOS or bipolar inputs.
It operates across ±6 V to ±18 V dual supplies (or 12–36 V single supply), supports full-rail input common-mode range up to VCC+, and maintains stable unity-gain performance without external compensation - confirmed by its 1 MHz GBP and 3.5 V/µs slew rate under 10 kΩ/100 pF load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables ultra-low-power multi-channel analog front-ends in portable test gear |
| Slew Rate | 3.5 V/µs - supports clean amplification of audio-band signals (≤100 kHz) with minimal distortion |
| Input Bias Current | 7 pA typical (TL064B grade) - preserves signal integrity when interfacing high-impedance sources like piezoelectric sensors |
| Gain-Bandwidth Product | 1 MHz - allows stable closed-loop gain ≥10 at 100 kHz, suitable for active filters and signal conditioning |
| Input Resistance | 10¹² Ω - prevents loading of high-Z transducers and electrochemical sensors |
| Common-Mode Range | ±11.5 V (min) with ±15 V supply - accepts inputs within 1.5 V of either rail, simplifying level-shifting design |
| Output Swing | ±13.5 V (typ.) into 10 kΩ - delivers near-rail output drive for ADC reference buffers and line drivers |
Pinout & Package
TL064BIDT is supplied in a 14-lead SOIC (SO-14) plastic micropackage, 3.9 mm wide, with 1.27 mm pitch and gull-wing leads - compatible with IPC-7351B SOIC14_390X175_P127_M.
| Pin/Terminal | Circuit Role | Design Meaning |

| 6 | Non-inverting Input (Amplifier B) | Matched input pair for Amplifier B; same bias and offset specs as Pins 1–2 |
| 7 | Output (Amplifier B) | Second independent output; shares thermal and supply coupling with other channels |
| 8 | Output (Amplifier C) | Third output; identical AC/DC specs to Pins 3 and 7; no crosstalk beyond 120 dB channel separation |
| 9 | Inverting Input (Amplifier C) | Third amplifier's inverting input; layout symmetry ensures matching with Pins 1 and 5 |
| 10 | Non-inverting Input (Amplifier C) | Third non-inverting input; guaranteed tracking within 10 µV/°C offset drift vs. other channels |
| 11 | VCC+ (Positive Supply) | Positive supply rail connection; supports up to +18 V; decoupling required within 10 mm |
| 12 | Output (Amplifier D) | Fourth output; fully specified for all electrical parameters including slew rate and noise |
| 13 | Inverting Input (Amplifier D) | Final inverting input; validated for operation down to −12 V common-mode with +15 V supply |
| 14 | Non-inverting Input (Amplifier D) | Final input pair; meets same Iib/Iio specs as all other channels (≤7 pA typ.) |
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 slew rate (13 V/µs), higher supply current (2.8 mA), lower input bias current (30 pA typ.) | Better for wideband active filters but unsuitable for battery-powered designs due to 7× higher current | Select TL074CDR only when bandwidth >10 MHz is required and power budget permits |
| RC4136N | Lower input offset voltage (2 mV max), wider supply range (±4 V to ±22 V), no internal compensation | Requires external compensation capacitor; better for custom high-precision DC-coupled stages | Choose RC4136N when offset-critical DC applications demand <2 mV Vio and board space allows compensation components |
Compared with TL064BIDT, TL074CDR trades ultra-low power for speed, while RC4136N sacrifices integration for tighter DC specs - making TL064BIDT optimal for space- and energy-constrained multi-channel analog systems where 1 MHz bandwidth suffices.

FAQ
What is the maximum operating supply voltage for TL064BIDT?
The absolute maximum supply voltage is ±18 V (or 36 V total across VCC+ and VCC−). Operation above ±15 V is permitted but reduces output swing margin and increases power dissipation; derating is recommended above ±16 V for continuous use in ambient temperatures exceeding 70°C.
Does TL064BIDT support single-supply operation?
Yes - it functions with a single supply from 12 V to 36 V. The input common-mode range extends to VCC− (ground), allowing direct interfacing with ground-referenced sensors. However, output swing remains asymmetric unless a virtual ground or split-rail converter is used.
How does TL064BIDT differ from TL064CDT?
TL064BIDT is rated for −40°C to +105°C operation and features tighter input offset voltage (2–5 mV max) and lower input bias current (≤7 pA typ.) versus TL064CDT (0°C to +70°C, 3–20 mV Vio, ≤10 pA Iib), making it suitable for extended-temperature industrial deployments.
Is external frequency compensation required for TL064BIDT?
No - TL064BIDT includes internal frequency compensation optimized for unity-gain stability. It drives capacitive loads up to 100 pF directly; larger loads require isolation resistors or external compensation per Figure 17 in the datasheet to prevent peaking or oscillation.
