Texas Instruments TL052CPSR

Overview

TL052CPSR from Texas Instruments is a dual FET-input operational amplifier with on-chip offset-voltage trimming, 4.5 MHz unity-gain bandwidth, 17.8 V/μs slew rate (±15 V), and 0.75 mV max input offset voltage at 25°C. It serves as a direct pin-compatible upgrade to TL072 and TL082 in precision analog signal conditioning circuits for test equipment and audio preamplifiers.

For engineers reviewing the TL052CPSR datasheet, TL052CPSR pinout, TL052CPSR application, or TL052CPSR equivalent, key selection criteria include its FET-input high-impedance interface capability (10¹² Ω), low 10.8 nV/√Hz input voltage noise at 1 kHz, and guaranteed operation across ±5 V to ±15 V dual supplies with rail-to-rail output swing limitations.

Technical Context

The TL052CPSR uses enhanced JFET-input process technology to achieve improved DC accuracy over TL07x/TL08x families while maintaining low noise floor and higher slew rate without increased quiescent current. Its internal architecture includes trimmed input-stage transistors for reduced VIO drift and optimized compensation for stable unity-gain operation with ≥60° phase margin.

Designed for dual-supply operation, it requires attention to common-mode input voltage limits (–11 V to +11 V at ±15 V) and output swing headroom (±11.5 V into 2 kΩ). It is not rated for single-supply use without external DC biasing or virtual-ground generation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual FET-input operational amplifier applications.

Compared with TL052CPSR, TL072CDR offers lower cost and wider legacy support but sacrifices DC accuracy and noise performance; OPA2134UA delivers superior noise and speed at higher quiescent current and price - TL052CPSR uniquely balances trimmed offset, FET-input Zin, and 4.5 MHz bandwidth within 12.8 mA total ICC.

FAQ

What is the maximum capacitive load the TL052CPSR can drive without oscillation?

The TL052CPSR is specified for stable operation with ≤10 pF load capacitance. Driving larger capacitive loads (e.g., >100 pF) risks peaking or oscillation due to phase margin degradation; adding a series resistor (e.g., 20–100 Ω) between the output and load restores stability. For 1000 pF loads, a 50 Ω series resistor typically suffices. Always verify stability under actual operating conditions using step-response testing.

Does the TL052CPSR support single-supply operation?

No, the TL052CPSR is designed exclusively for dual-supply operation (±5 V to ±15 V). Its input common-mode range and output swing are specified relative to symmetric rails. Operating from a single supply requires external DC biasing (e.g., mid-rail virtual ground via TLE2426) and careful attention to input voltage limits - TI does not characterize or guarantee performance under single-supply conditions.

How does the TL052CPSR differ from the TL052ACPSR variant?

The TL052CPSR (C-suffix) is characterized over 0°C to 70°C with 0.75 mV max input offset voltage at 25°C, while the TL052ACPSR (AC-suffix) offers tighter 0.57 mV max VIO at 25°C and improved temperature coefficient (23 μV/°C vs 25 μV/°C). Both share identical pinout, package, bandwidth, and slew rate - the AC grade targets higher-precision applications where initial offset and drift are critical.

Can unused channels in the TL052CPSR be left floating?

No - unused op-amp channels must not be left floating. TI recommends configuring them as unity-gain voltage followers with inputs tied to a valid common-mode voltage (e.g., mid-supply via resistor divider) to prevent phase reversal, oscillation, or excessive current draw. Leaving inputs unconnected may cause unpredictable output states and increased power consumption.

What is the thermal resistance (θJA) of the TL052CPSR in its PS package?

The TL052CPSR in the PS (SOP-8) package has a junction-to-ambient thermal resistance (θJA) of 95°C/W, as specified in TI's SLOS178B datasheet Section 4.2. This value assumes standard JEDEC 2-layer board conditions; actual thermal performance depends on PCB copper area, airflow, and nearby heat sources - derate maximum ambient temperature accordingly for continuous full-load operation.
