Texas Instruments TL061CPSR

Overview

TL061CPSR from Texas Instruments is a single-channel, low-power JFET-input operational amplifier designed for precision analog signal conditioning in cost-sensitive industrial and consumer systems. It delivers 200 µA typical supply current, 3.5 V/µs slew rate, ±11 V common-mode input range (including V_CC+), and 10¹² Ω input resistance - enabling high-impedance sensor interfacing in battery-powered tablets and white goods.

For engineers reviewing the TL061CPSR datasheet, TL061CPSR pinout, TL061CPSR application, or TL061CPSR equivalent, key selection criteria include its JFET-input architecture for ultra-low bias current (30 pA typ), rail-to-rail-compatible input stage, output short-circuit protection, and SOIC-8 packaging suitable for space-constrained PCB layouts.

Technical Context

The TL061CPSR implements a fully differential JFET-input stage followed by a high-gain CMOS transconductance amplifier and class-AB output stage, with internal frequency compensation ensuring unity-gain stability. Its input stage supports common-mode voltages up to V_CC+, eliminating level-shifting requirements in single-supply configurations.

It operates across 0°C to 70°C (Commercial grade), accepts dual supplies from ±5 V to ±15 V, and achieves 1 MHz unity-gain bandwidth with 86 dB CMRR and 95 dB PSRR - making it suitable for DC-coupled instrumentation, active filters, and voltage-controlled oscillators where low power and high impedance are critical.

Key Specifications

Pinout & Package

TL061CPSR is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 6.00 mm, with standard 1.27 mm pitch and gull-wing leads compatible with automated SMT assembly.

FAQ

What is the maximum supply voltage rating for TL061CPSR?

The absolute maximum supply voltage for TL061CPSR is ±18 V across V_CC+ and V_CC–. Operation beyond this risks permanent damage. For reliable long-term use, TI specifies ±15 V as the recommended maximum operating supply, supporting full parameter performance across 0°C to 70°C ambient temperature.

Does TL061CPSR support single-supply operation?

Yes, TL061CPSR supports single-supply operation due to its common-mode input voltage range extending to V_CC+. When powered from +15 V and ground, inputs can accept signals up to +15 V. However, output swing remains limited to approximately +10 V (vs ground), so proper biasing of the non-inverting input is required for AC-coupled applications.

How do I adjust input offset voltage on TL061CPSR?

TL061CPSR provides dedicated offset null pins (1 and 5) for external trimming. Connect a 10-kΩ potentiometer between V_CC– and V_CC+, with its wiper to pin 1 and either end to pin 5. Adjust until output voltage equals mid-supply under zero-input conditions - achieving sub-millivolt DC accuracy in precision gain stages.

Is TL061CPSR pin-compatible with other TL06x variants?

TL061CPSR shares identical pinout with all TL061 variants (e.g., TL061ACPSR, TL061BCPSR) in SOIC-8 packaging. However, it is not pin-compatible with TL062 or TL064 - those have different channel counts and pin assignments. Always verify package marking and orderable part number before substitution.

What thermal considerations apply to TL061CPSR in SOIC-8?

In SOIC-8 (D package), TL061CPSR has a junction-to-ambient thermal resistance (R_θJA) of 97°C/W. At 250 µA supply current and ±15 V supplies, power dissipation is ~7.5 mW - resulting in <1°C junction rise above ambient. No heatsinking is required, but 0.1 µF ceramic bypass capacitors on both supplies are mandatory for stability.
