Texas Instruments TL062IDR

Overview

TL062IDR from Texas Instruments is a dual 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, and 1 MHz unity-gain bandwidth - enabling precision DC-coupled amplification and filtering in battery-powered or thermally constrained designs.

For engineers reviewing the TL062IDR datasheet, TL062IDR pinout, TL062IDR application, or TL062IDR equivalent, key selection criteria include its JFET-input architecture for picoampere-level bias current, rail-to-rail compatible input stage (V_CM includes V_CC+), output short-circuit protection, and SOIC-8 packaging suitable for space-constrained PCB layouts.

Technical Context

The TL062IDR implements a two-stage JFET-input transconductance amplifier with internal frequency compensation, delivering stable unity-gain operation without external components. Its differential pair input stage achieves 10¹² Ω input resistance and sub-10 pA input bias current at 25°C, while maintaining CMRR ≥80 dB and PSRR ≥80 dB across –40°C to 85°C.

Designed as a lower-power counterpart to the TL072 and TL082 families, the TL062IDR retains comparable AC performance (1 MHz GBW, 3.5 V/µs slew) but reduces quiescent current by ~50%. It supports dual-supply operation from ±5 V to ±15 V and features latch-up-free silicon construction with integrated EMI/RF filters.

Key Specifications

FAQ

What is the maximum supply voltage rating for TL062IDR?

The TL062IDR has an absolute maximum supply voltage rating of ±18 V across V_CC+ and V_CC–. For reliable long-term operation, TI specifies recommended operating conditions of ±5 V to ±15 V. Exceeding ±15 V may increase power dissipation beyond safe limits and accelerate parameter drift over time, especially at elevated ambient temperatures.

Does TL062IDR support single-supply operation?

Yes, TL062IDR supports single-supply operation when the negative rail is tied to ground (V_CC– = 0 V) and the input common-mode range is biased appropriately. Its input stage accepts voltages up to V_CC+, enabling rail-to-rail input capability - however, output swing is limited to approximately 1.5 V from each rail, so mid-rail biasing (e.g., V_CC+/2) is required for AC-coupled signals.

How does TL062IDR compare to TL072IDR in terms of power efficiency?

TL062IDR draws only 200 µA per amplifier versus 1.4 mA for TL072IDR - a 86% reduction in quiescent current. This makes TL062IDR ideal for multi-channel, battery-powered, or thermally constrained systems where cumulative supply current must remain below 1 mA. While TL072IDR offers higher slew rate and lower noise, TL062IDR maintains adequate 1 MHz bandwidth and 3.5 V/µs slew for most industrial signal conditioning tasks.

Is TL062IDR pin-compatible with other dual op-amps in SOIC-8 packages?

TL062IDR uses the industry-standard SOIC-8 pinout defined for dual op-amps (pin 1 = OUT A, pin 2 = IN– A, pin 3 = IN+ A, pin 4 = V_CC–, pin 5 = IN+ B, pin 6 = IN– B, pin 7 = OUT B, pin 8 = V_CC+). It is pin-compatible with TL072, TL082, LM358, and OP297 in SOIC-8 packages, though electrical characteristics (bias current, supply current, noise) differ significantly between families.

What thermal considerations apply to TL062IDR in SOIC-8 packaging?

TL062IDR in SOIC-8 (D package) has a junction-to-ambient thermal resistance (R_θJA) of 97°C/W. At maximum rated supply (±15 V) and full output swing, power dissipation per amplifier is ≤7.5 mW - resulting in <1.5°C junction rise above ambient under typical PCB layout. No heatsinking is required, but 2–4 thermal vias under the exposed pad (if present) and copper pour on adjacent layers improve long-term reliability at 85°C ambient.
