Product details

Overview

TL064BID from STMicroelectronics is a low-power JFET-input quad operational amplifier designed for precision analog signal conditioning in space-constrained industrial and instrumentation systems. It delivers 3.5 V/µs slew rate, ±15 V input common-mode range (up to V_CC), 200 µA supply current per amplifier, 1 MHz gain-bandwidth product, and 10¹² Ω input resistance - enabling high-impedance sensor interfacing and rail-to-rail-compatible operation in ±5 V to ±18 V supplies.

For engineers reviewing the TL064BID datasheet, TL064BID pinout, TL064BID application, or TL064BID equivalent, this device is selected for low-noise, low-quiescent-current amplification where input bias current below 7 pA (typ.), offset voltage under 5 mV (max), and channel separation of 120 dB support multi-channel signal integrity in data acquisition, audio distribution, and active filter designs.

Technical Context

The TL064BID 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-impedance JFET input stage enables ultra-low input bias currents (≤7 pA typ.) and low temperature drift (10 µV/°C max ΔV_io/ΔT), critical for precision integrators and photodiode transimpedance stages.

It operates across –40°C to +105°C with supply voltages from ±5 V to ±18 V, supports rail-swing output up to ±13.5 V (with ±15 V supplies), and maintains 86 dB common-mode rejection and 95 dB supply rejection - making it suitable for mixed-signal environments with noisy power rails and wide dynamic input ranges.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Current	200–250 µA per amplifier - enables battery-powered or energy-sensitive systems with four independent gain stages.
Slew Rate	3.5 V/µs - supports 100 kHz small-signal bandwidth in unity-gain follower configurations.
Input Bias Current	≤7 pA (typ.) - preserves signal integrity in high-impedance sensor nodes (e.g., pH electrodes, piezoelectric sensors).
Input Offset Voltage	2–5 mV (max) - ensures ≤0.03% gain error in 10 V full-scale instrumentation amplifiers.
Gain-Bandwidth Product	1 MHz - allows stable closed-loop gains up to 100 at 10 kHz without external compensation.
Common-Mode Range	±11.5 V to +15 V / –12 V - accepts inputs beyond negative rail and up to positive supply, simplifying level-shifting circuits.
Channel Separation	120 dB - prevents crosstalk between adjacent channels in multi-channel data loggers or audio mixers.

Pinout & Package

TL064BID is supplied in SO-14 (plastic micropackage), a 14-pin surface-mount package with 1.27 mm pitch, 8.55–8.75 mm body length, and 5.8–6.2 mm width - optimized for automated assembly and thermal performance (R_thJA = 105 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
1	Inverting Input (Amplifier A)	High-impedance differential input node for first op-amp; requires guarding in high-Z applications.
2	Non-inverting Input (Amplifier A)	Reference input for A-channel; matches pin 1 in layout symmetry and parasitic balance.
3	Output (Amplifier A)	Class-AB output stage capable of ±13.5 V swing into 10 kΩ load with <10% overshoot.
4	V_CC– (Negative Supply)	Ground reference for dual-supply operation; must be decoupled within 1 cm of pin with 100 nF ceramic.
5	Inverting Input (Amplifier B)	Second independent high-Z input; electrically isolated from A-channel per datasheet layout guidelines.
6	Non-inverting Input (Amplifier B)	Matched pair with pin 5; used for differential sensing or parallel gain staging with A-channel.
7	Output (Amplifier B)	Independent output with same drive capability as pin 3; supports individual feedback networks.
8	V_CC+ (Positive Supply)	Primary power rail; supplies all four amplifiers; requires local 100 nF + 10 µF bulk decoupling.
9	Inverting Input (Amplifier C)	Third channel input; shares substrate with pins 1–7 but exhibits >120 dB inter-channel isolation.
10	Non-inverting Input (Amplifier C)	Enables three-channel simultaneous signal conditioning without cross-talk degradation.
11	Output (Amplifier C)	Delivers identical AC/DC performance as pins 3 and 7; validated for simultaneous 100 kHz operation.
12	Inverting Input (Amplifier D)	Fourth channel input; completes quad configuration for full-system analog front-end integration.
13	Non-inverting Input (Amplifier D)	Supports independent reference biasing; used in multi-stage active filters or summing junctions.
14	Output (Amplifier D)	Final output stage; characterized for stability with 100 pF capacitive loads per Figure 14 in datasheet.

Key Features

Feature	Design Value

Internal Frequency Compensation	Guarantees unity-gain stability without external components across all operating conditions and loads.
Output Short-Circuit Protection	Withstands indefinite short to either rail or ground while limiting dissipation to safe junction temperatures.

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), lower input noise (18 nV/√Hz), but higher I_ib (30 pA typ.) and ICC (2.8 mA total).	Better for wideband audio or fast pulse amplification; unsuitable for ultra-low-power or high-Z DC-coupled sensors.	Select when bandwidth >10 MHz or noise <20 nV/√Hz is required, and supply current >1 mA is acceptable.
RC4136N	Lower V_io (0.5 mV max), wider temp range (–55°C to +125°C), but no SO-14 option and higher cost.	Preferred for military/aerospace-grade precision instrumentation where offset drift and extended temperature are critical.	Choose for <1 mV offset-critical applications with full military temp range; verify DIP14 footprint compatibility.

Compared with TL064BID, TL074CDR trades ultra-low power for speed and noise performance, while RC4136N prioritizes DC precision and ruggedness over cost and package flexibility - making TL064BID optimal for balanced industrial signal conditioning where quiescent current, input impedance, and SO-14 manufacturability are primary constraints.

FAQ

What is the maximum recommended supply voltage for TL064BID?

The absolute maximum supply voltage is ±18 V, but ST specifies reliable operation across ±5 V to ±18 V. For long-term reliability and thermal safety, operation at ±15 V is recommended - delivering optimal slew rate (3.5 V/µs), output swing (±13.5 V), and input common-mode range (±11.5 V to +15 V / –12 V) per datasheet Table 3.

Does TL064BID require external compensation capacitors?

No. TL064BID features internal frequency compensation optimized for unity-gain stability across all standard loads (including 100 pF capacitive loads). External compensation is unnecessary for gains ≥1; however, for gains <1 (inverter configurations), stability should be verified with actual PCB layout parasitics using the test circuit in Figure 14 of the datasheet.

Can TL064BID drive capacitive loads directly?

Yes - TL064BID is characterized to drive up to 100 pF capacitive loads without oscillation, as confirmed in Figure 14 (large-signal pulse response) and parameter measurement section. For loads >100 pF, a series isolation resistor (typically 22–100 Ω) placed between output and capacitance restores phase margin and prevents peaking.

How does TL064BID differ from TL064CDR in terms of temperature grade?

TL064BID is rated for –40°C to +105°C operation (industrial grade), while TL064CDR is specified for 0°C to +70°C (commercial grade). This makes TL064BID suitable for deployment in outdoor equipment, motor controls, and factory-floor instrumentation where ambient extremes exceed 70°C or fall below 0°C.
