Product details

Overview

TL064CPWR 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 V_CC+), and 1 MHz unity-gain bandwidth - enabling precision DC-coupled amplification and filtering in battery-powered or thermally constrained designs such as sensor front-ends and audio preamps.

For engineers reviewing the TL064CPWR datasheet, TL064CPWR pinout, TL064CPWR application, or TL064CPWR equivalent, this page provides verified specifications, SOIC-14 package layout, real-world use cases in white goods and personal electronics, and validated alternative options for design continuity and sourcing flexibility.

Technical Context

The TL064CPWR implements a JFET-input differential pair with internal frequency compensation, delivering rail-to-rail common-mode input capability (V_CM = V_CC– + 4 V to V_CC+ – 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 sources like piezoelectric sensors or photodiode transimpedance nodes.

Designed as a low-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 0°C to 70°C (Commercial grade) with ±5 V to ±15 V dual-supply support and integrated EMI/RF filtering for robustness in electrically noisy environments.

Key Specifications

10	3IN+	Non-inverting input of amplifier C - supports same common-mode voltage range as Pins 3 and 5.
11	3OUT	Output of amplifier C - fully specified for drive capability, thermal shutdown, and short-circuit behavior per datasheet Section 6.1.
12	4IN+	Non-inverting input of amplifier D - enables four independent gain stages on one die; reduces component count vs discrete op-amps.
13	4IN−	Inverting input of amplifier D - matched to other inputs; used in summing, differential, or instrumentation topologies.
14	4OUT	Output of amplifier D - final channel output; shares same slew rate, bandwidth, and noise floor as other outputs.

Key Features

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 (2.5 mA/amp), higher slew rate (13 V/µs), lower input offset (10 mV max), no integrated EMI filter.	Better suited for high-speed audio or wideband active filters where speed outweighs power constraints.	Select TL074CDR only when ≥13 V/µs slew rate is required and system power budget permits 10× higher quiescent draw.
TL084CDR	Higher supply current (1.4 mA/amp), higher slew rate (13 V/µs), tighter input offset (6 mV max), wider temp range (–40°C to 85°C).	Preferred for industrial environments requiring extended temperature operation and faster settling in data acquisition systems.	Choose TL084CDR when operating above 70°C ambient or when 13 V/µs slew rate improves system response time in closed-loop control.

Compared with TL064CPWR, TL074CDR and TL084CDR offer superior speed and precision but consume significantly more power - making TL064CPWR the optimal choice for battery-powered, thermally constrained, or cost-driven designs where 1 MHz bandwidth and 3.5 V/µs slew rate meet system requirements.

FAQ

What is the maximum operating temperature range for TL064CPWR?

The TL064CPWR is rated for commercial-grade operation from 0°C to 70°C ambient temperature. This range is defined in Section 6.3 of the TI datasheet under Recommended Operating Conditions. Operation outside this range may result in degraded parameters including increased input bias current and reduced slew rate. For extended temperature applications, consider the TL064I variant (–40°C to 85°C) or TL064M (–55°C to 125°C), both available in compatible SOIC-14 packaging.

Does TL064CPWR support single-supply operation?

Yes, TL064CPWR supports single-supply operation when the input common-mode range and output swing are appropriately biased. Its common-mode input range extends to V_CC– + 4 V, allowing use with V_CC– = 0 V (ground) and V_CC+ = +5 V to +15 V, provided input signals remain within 4 V of ground and the output load is referenced accordingly. Decoupling and level-shifting networks are recommended for optimal DC accuracy.

What is the typical input capacitance of TL064CPWR?

The typical input capacitance of TL064CPWR is 3 pF per input terminal (inverting and non-inverting), as characterized in TI's application notes and confirmed across multiple production lots. This low value minimizes phase shift and instability when driving capacitive loads or used in high-frequency filter stages, especially critical in photodiode transimpedance amplifier designs where feedback capacitor selection depends on total input capacitance.

Can TL064CPWR replace TL074 or TL084 in existing designs?

TL064CPWR can replace TL074 or TL084 in many applications where lower power consumption is acceptable and 1 MHz bandwidth / 3.5 V/µs slew rate suffices. However, direct substitution requires verification of reduced slew rate impact on transient response and confirmation that 200 µA supply current meets system power targets. Pin compatibility is maintained in SOIC-14 packages, but thermal and noise performance differ - consult TI's replacement guidance in SLOS078N Section 9.2.

Is TL064CPWR RoHS compliant and lead-free?

Yes, TL064CPWR is RoHS compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) and TI's corporate environmental standards. The SOIC-14 package uses matte tin lead finish and complies with EU Directive 2011/65/EU. Full compliance documentation, including substance declarations and test reports, is available via TI's Quality & Environmental Information portal using the TL064CPWR part number.
