Product details

Overview

TL064IDRG4 from Texas Instruments is a quad JFET-input operational amplifier designed for low-power, high-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 (with V_CC+ inclusion), and 10¹² Ω input resistance - enabling precision DC-coupled amplification in battery-powered sensors and audio front-ends.

For engineers reviewing the TL064IDRG4 datasheet, TL064IDRG4 pinout, TL064IDRG4 application, or TL064IDRG4 equivalent, key selection criteria include its JFET-input architecture for ultra-low bias current (≤200 pA at 25°C), rail-to-rail-compatible input stage, quad-channel SOIC-14 packaging, and operation across –40°C to 85°C ambient temperature.

Technical Context

The TL064IDRG4 implements a fully differential JFET-input stage with internal frequency compensation, supporting stable unity-gain operation without external components. Its high-impedance inputs and low input offset current (5 pA typical) minimize loading on high-Z sources like piezoelectric sensors and photodiode transimpedance nodes.

It features output short-circuit protection and latch-up-free operation under transient overvoltage conditions. The device maintains ≥120 dB crosstalk attenuation between channels, ensuring isolation in multi-channel instrumentation and active filter banks.

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 vs 0.8 mA total), 13 V/µs slew rate, tighter V_IO spec (3 mV max)	Better for wideband active filters and higher-speed signal chains where power budget permits	Select TL074CDR when bandwidth >3 MHz and lower input offset are required; TL064IDRG4 preferred for sub-1 mA systems
TL084CDR	Higher noise density (18 nV/√Hz vs 30 nV/√Hz), 13 V/µs slew rate, same 2.5 mA supply current	Optimized for general-purpose audio and video signal routing where noise floor is less critical than speed	Choose TL084CDR for legacy designs requiring pin compatibility with older TL08x-based layouts; TL064IDRG4 offers superior power efficiency

Compared with TL074CDR and TL084CDR, TL064IDRG4 trades bandwidth and noise performance for 90% lower quiescent current - making it the only quad JFET op amp in SOIC-14 qualified for continuous operation in energy-harvesting and always-on sensor nodes.

FAQ

What is the maximum supply voltage rating for TL064IDRG4?

The absolute maximum supply voltage for TL064IDRG4 is ±18 V (36 V total). However, the recommended operating range is ±5 V to ±15 V. Operation beyond ±15 V risks exceeding thermal limits and degrading long-term reliability, especially in the SOIC-14 package where R_θJA = 86°C/W. Always verify power dissipation using P_D = (V_CC+ − V_CC−) × I_CC × 4 for the full quad device.

Does TL064IDRG4 support single-supply operation?

Yes, TL064IDRG4 supports single-supply operation with V_CC– tied to ground and V_CC+ at +5 V to +15 V. Its common-mode input range extends to V_CC+, allowing input signals referenced to the positive rail. Output swing remains limited to approximately 0 V to V_CC+ − 1.5 V, so level-shifting or rail-splitting may be needed for bipolar signal handling in true single-supply configurations.

What is the input offset voltage specification for TL064IDRG4?

TL064IDRG4 has a maximum input offset voltage of 15 mV at 25°C and 20 mV over the full operating temperature range (–40°C to +85°C). This value applies to the "C" grade variant indicated by the "I" suffix in TL064I, which aligns with the TL064IDRG4 ordering code. The typical offset is 3 mV, and temperature coefficient is 10 µV/°C - enabling predictable drift compensation in precision DC-coupled stages.

How does TL064IDRG4 compare to TL074 in terms of power efficiency?

TL064IDRG4 draws only 200 µA per amplifier (800 µA total), whereas TL074 consumes 2.5 mA per amplifier (10 mA total). This represents a 92% reduction in quiescent current. For battery-powered devices requiring weeks of runtime, TL064IDRG4 extends operational life significantly - e.g., a 200 mAh coin cell would power TL064IDRG4 continuously for >100 days versus <2 days for TL074 under identical conditions.

Is TL064IDRG4 pin-compatible with other quad op amps in SOIC-14?

TL064IDRG4 uses the industry-standard quad op amp pinout defined in Figure 5-3 of the TI datasheet (SLOS078N), matching TL074, TL084, and LM324 families. Pin 1 is 1OUT, Pin 2 is 1IN–, Pin 3 is 1IN+, Pin 4 is V_CC+, etc. However, electrical differences - particularly supply current, slew rate, and input bias - require circuit validation before drop-in replacement in existing TL074/TL084 designs.
