Product details

Overview

TL064CPWG4 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 precision DC-coupled amplification and filtering in battery-powered or thermally constrained applications such as sensor front-ends and portable audio.

For engineers reviewing the TL064CPWG4 datasheet, TL064CPWG4 pinout, TL064CPWG4 application, or TL064CPWG4 equivalent, key selection criteria include its JFET-input architecture for pA-level bias current, SOIC-14 packaging for board space efficiency, rail-to-rail compatible input stage, and guaranteed operation across 0°C to 70°C ambient temperature with ±5 V to ±15 V dual-supply flexibility.

Technical Context

The TL064CPWG4 implements a fully differential JFET-input stage followed by a high-gain CMOS-compatible output stage, internally compensated for stable unity-gain operation. Its input stage supports common-mode voltages up to V_CC+, eliminating level-shifting requirements in single-supply configurations when biased appropriately.

Each of the four independent amplifiers features matched electrical characteristics - including <10 µV/°C input offset drift, 120 dB crosstalk attenuation, and 86 dB CMRR - ensuring consistent performance across multi-channel signal paths without inter-amplifier interaction under normal operating conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Current (per amp)	200 µA typical - enables ultra-low quiescent power in always-on sensor interfaces or multi-amp systems where thermal budget is critical.
Input Bias Current	30 pA typical at 25°C - preserves signal integrity in high-impedance source networks (e.g., piezoelectric sensors, photodiode transimpedance stages).
Slew Rate	3.5 V/µs typical - supports faithful reproduction of audio-band signals (<100 kHz) and fast-settling DC-coupled control loops.
Unity-Gain Bandwidth	1 MHz - allows stable closed-loop gain configurations up to G = 10 with >60° phase margin using standard compensation techniques.
Common-Mode Input Range	–12 V to +15 V (with ±15 V supplies) - includes V_CC+, permitting direct connection of inputs to positive rails in non-inverting configurations.
Input Offset Voltage	3 mV max at 25°C - ensures ≤±15 mV output error in unity-gain buffers driving 10 kΩ loads, suitable for 12-bit ADC front-ends.
ESD Rating (HBM)	2000 V - meets industrial handling requirements without additional protection circuitry in controlled assembly environments.

Pinout & Package

TL064CPWG4 is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package measuring 8.65 mm × 6.00 mm, optimized for automated surface-mount assembly and moderate-power dissipation (R_θJA = 86°C/W).

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Output of first amplifier - directly drives loads up to 10 kΩ while maintaining ±10 V swing with ±15 V supplies.
2	1IN–	Inverting input of first amplifier - high-impedance node (10¹² Ω) requiring guarded layout to minimize leakage-induced offset.
3	1IN+	Non-inverting input of first amplifier - accepts common-mode voltages up to V_CC+, enabling rail-referenced sensing.
4	V_CC+	Positive power supply terminal - must be decoupled locally with ≥0.1 µF ceramic capacitor to suppress high-frequency noise coupling.
5	2IN+	Non-inverting input of second amplifier - electrically isolated from other channels; shares no internal substrate coupling with adjacent amps.
6	2IN–	Inverting input of second amplifier - matched to Pin 2 for differential pair consistency across all four amplifiers.
7	2OUT	Output of second amplifier - identical AC/DC specs to Pin 1; crosstalk attenuation >120 dB prevents inter-channel interference.
8	V_CC–	Negative power supply terminal - reference for both input and output stages; requires symmetrical decoupling to Pin 4.
9	3IN–	Inverting input of third amplifier - maintains same bias current and offset voltage distribution as Pins 2 and 6.
10	3IN+	Non-inverting input of third amplifier - supports same common-mode range and input impedance as Pins 3 and 5.
11	3OUT	Output of third amplifier - fully specified for drive capability, settling time, and overload recovery per channel.
12	4IN+	Non-inverting input of fourth amplifier - completes quad functional set; no shared pins or internal routing with other channels.
13	4IN–	Inverting input of fourth amplifier - matches parametric behavior of Pins 2, 6, and 9 within production tolerances.
14	4OUT	Output of fourth amplifier - independently buffered; capable of sourcing/sinking ≥10 mA short-circuit current with thermal foldback protection.

Key Features

Feature	Design Value
JFET-input architecture	Delivers 30 pA typical input bias current and 10¹² Ω input resistance - essential for preserving signal fidelity in high-Z sensor interfaces and precision integrators.

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), faster slew rate (13 V/µs), lower input bias current (3 pA), but no V_CC+-inclusive input range.	Better suited for wideband active filters or high-speed signal paths where power budget permits; less tolerant of rail-referenced inputs.	Select TL074CDR only when bandwidth >3 MHz or slew rate >10 V/µs is required; verify input common-mode limits match system topology.
TL084CDR	Higher supply current (1.4 mA/amp), higher input bias current (30 pA same as TL064), wider GBW (3 MHz), no V_CC+ input support.	Preferred for general-purpose AC-coupled amplification where speed outweighs quiescent power concerns.	Choose TL084CDR for legacy designs requiring drop-in replacement with improved AC performance; confirm thermal design accommodates 7× higher power dissipation.

Compared with TL074CDR and TL084CDR, TL064CPWG4 provides the lowest quiescent power and unique V_CC+-inclusive input range - making it optimal for battery-operated, rail-sensing, or thermally constrained multi-channel analog systems where speed is secondary to efficiency and input flexibility.

FAQ

What is the maximum supply voltage rating for TL064CPWG4?

The absolute maximum supply voltage for TL064CPWG4 is ±18 V across V_CC+ and V_CC–. However, the recommended operating range is ±5 V to ±15 V. Operation beyond ±15 V may degrade long-term reliability and is not characterized for parametric performance - always refer to Section 6.1 Absolute Maximum Ratings in the official TL064CPWG4 datasheet for safe derating guidelines.

Does TL064CPWG4 support rail-to-rail input or output operation?

TL064CPWG4 supports rail-to-rail input operation - its common-mode input range extends to V_CC+, allowing direct connection to the positive supply rail. However, its output swing is limited to ±10 V (minimum) with ±15 V supplies and does not achieve true rail-to-rail output. For full rail-to-rail output capability, consider modern alternatives like the OPA4340 series.

Can TL064CPWG4 be used with a single supply?

Yes, TL064CPWG4 can operate from a single supply (e.g., +15 V and ground) provided the input common-mode voltage remains within specification (≥4 V above V_CC–). This requires biasing inputs and outputs at mid-supply using resistive dividers or dedicated reference ICs. The device's V_CC+-inclusive input range simplifies single-supply design compared to many legacy op-amps.

What is the thermal resistance (R_θJA) of TL064CPWG4 in its SOIC-14 package?

The junction-to-ambient thermal resistance (R_θJA) for TL064CPWG4 in the SOIC-14 (D) package is 86°C/W, as specified in Section 6.6 Thermal Information of the datasheet. This value assumes standard JEDEC 2-layer board conditions; actual thermal performance improves with added copper pour and thermal vias beneath the exposed pad (if present) or adjacent ground planes.

Is TL064CPWG4 pin-compatible with other TL06x variants like TL064CN or TL064ACN?

TL064CPWG4 shares identical pinout and electrical functionality with all TL064x variants in SOIC-14 packaging (e.g., TL064CN, TL064ACN), differing only in temperature grade (C = 0°C to 70°C), screening level, and packaging markings. No PCB changes are required when substituting within the same package type, though parameter distributions (e.g., input offset voltage) vary per grade.
