Product details

Overview

TL064ING4 from Texas Instruments is a quad JFET-input operational amplifier designed for low-power, high-input-impedance analog signal conditioning in cost-sensitive systems. It delivers 200 µA per amplifier supply current, 3.5 V/µs typical slew rate, ±11 V common-mode input range (including V_CC+), and 1 MHz unity-gain bandwidth - enabling use in battery-powered audio preamps and sensor front-ends.

For engineers reviewing the TL064ING4 datasheet, TL064ING4 pinout, TL064ING4 application, or TL064ING4 equivalent, key selection criteria include its JFET-input stage (10¹² Ω input resistance), rail-to-rail-compatible input voltage range, low 5 pA typical input offset current, and SOIC-14 package suitability for space-constrained industrial control modules.

Technical Context

The TL064ING4 implements a fully differential JFET-input stage with internal frequency compensation, delivering stable unity-gain operation without external components. Its architecture supports wide common-mode input range (V_CC– + 4 V to V_CC+ – 4 V) and output short-circuit protection across –40°C to 85°C ambient operation.

It features integrated EMI/RF filtering and 1.5 kV HBM ESD rating, making it suitable for noisy environments like white goods motor control interfaces. The device maintains 120 dB crosstalk attenuation between channels, ensuring minimal inter-channel interference in multi-signal acquisition systems.

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 2.8 mA supply current per amplifier; 13 V/µs slew rate; tighter 3 mV max V_IO	Better for wideband audio or fast-settling data acquisition where power is not constrained	Select TL074CDR when bandwidth >3 MHz or slew rate >10 V/µs is required; avoid in battery-powered systems
TL084CDR	Higher 1.4 mA supply current; 13 V/µs slew rate; lower 10 pA I_IB at 25°C but higher temp drift	Preferred for precision instrumentation requiring lower input bias current drift over temperature	Choose TL084CDR for 0°C–70°C applications needing improved I_IB stability; TL064ING4 remains optimal for <250 µA budgets

Compared with TL074CDR and TL084CDR, TL064ING4 uniquely balances ultra-low power (200 µA), JFET-input integrity (10¹² Ω), and SOIC-14 compatibility - making it the only option among the three viable for multi-channel, long-life portable electronics.

FAQ

What is the maximum operating temperature range for TL064ING4?

The TL064ING4 is rated for operation from –40°C to +85°C ambient temperature. This industrial-grade range supports deployment in white goods control boards, HVAC systems, and portable medical devices exposed to variable environmental conditions. The device maintains specified electrical performance - including 200 µA supply current and 3.5 V/µs slew rate - across this full range, as verified in TI's TL064I characterization data.

Does TL064ING4 require external compensation capacitors?

No, TL064ING4 does not require external compensation capacitors. It features internal frequency compensation optimized for unity-gain stability in standard configurations like voltage followers or non-inverting amplifiers. This eliminates layout complexity and component count in space-constrained designs such as wearable health monitors or compact sensor modules using TL064ING4.

Can TL064ING4 operate from a single 5-V supply?

Yes, TL064ING4 can operate from a single 5-V supply when configured with appropriate input biasing. Its common-mode input range extends to V_CC+, allowing the non-inverting input to accept signals up to 5 V. However, output swing is limited to approximately 0.5 V to 4.5 V under load - so signal headroom must be planned accordingly in single-supply TL064ING4 implementations.

What is the input offset voltage specification for TL064ING4?

TL064ING4 has a maximum input offset voltage of 6 mV at 25°C and 20 mV across the full –40°C to +85°C operating range. This value is consistent with the TL064I grade per TI's SLOS078N datasheet. For precision applications requiring tighter offset, designers may select the TL064AC variant (3 mV max at 25°C), but TL064ING4 remains optimal where low power and cost are primary constraints.

Is TL064ING4 pin-compatible with other quad op amps in SOIC-14 packages?

TL064ING4 uses the industry-standard SOIC-14 pinout defined for quad op amps (e.g., pins 1/7/8/14 for outputs, 2/6/10/13 for inverting inputs). It is mechanically and functionally pin-compatible with TL074, TL084, and LM324 families in SOIC-14 - though electrical differences (e.g., supply current, input bias) require validation in the target circuit before substitution.
