Product details
Overview
TL052IP from Texas Instruments is a dual JFET-input operational amplifier with on-chip offset-voltage trimming, 4.5 MHz unity-gain bandwidth, 17.8 V/μs slew rate (±15 V), and 0.65 mV max input offset voltage at 25°C. It operates from ±5 V to ±15 V supplies and delivers rail-to-rail output swing into 2 kΩ loads in precision analog signal conditioning circuits.
For engineers reviewing the TL052IP datasheet, TL052IP pinout, TL052IP application, or TL052IP equivalent, this page provides verified electrical specifications, dual-channel pin mapping for SOIC-8 and PDIP-8 packages, FET-input performance context versus TL072/TL082, and validated alternatives for low-noise, low-offset op-amp upgrades.
Technical Context
The TL052IP uses enhanced JFET input stages with on-die trimming to achieve sub-millivolt DC offset stability across temperature. Its architecture balances high input impedance (10¹² Ω) and bipolar-like output drive capability without increased quiescent current-maintaining 8.4 mA typical supply current at ±15 V.
It features 106 dB crosstalk attenuation between channels, 92 dB common-mode rejection ratio (CMRR) at 25°C, and stable 60° phase margin with 2 kΩ/25 pF load-enabling reliable use in multi-stage instrumentation amplifiers and active filters without external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual FET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CP | Higher 10 mV max VIO, 3 V/μs slew rate, no on-chip trimming | Acceptable where offset drift <5 μV/°C and bandwidth <1 MHz suffice | Lower-cost option when precision DC performance is not required |

FAQ
What is the maximum operating supply voltage for TL052IP?
The TL052IP has an absolute maximum supply voltage rating of ±18 V. However, it is fully specified and characterized for operation from ±5 V to ±15 V. Operating beyond ±15 V may exceed guaranteed performance limits for parameters like input offset voltage, CMRR, and output swing-even if within absolute ratings. For reliable design, stay within the recommended ±5 V to ±15 V range per the SLOS178B datasheet.
Does TL052IP support single-supply operation?
TL052IP is designed for dual-supply operation and does not feature rail-to-rail input or output. When used with single supplies, DC biasing of both inputs to mid-rail (e.g., VCC/2) and termination of loads to a virtual ground (e.g., TI TLE2426) are mandatory. Input common-mode range is limited to –1 V to +4 V at ±5 V supply, so direct single-supply use without level-shifting circuitry will result in clipping or malfunction.
How does TL052IP differ from TL082 in practical circuit design?
TL052IP improves upon TL082 with on-chip offset trimming (0.65 mV vs. 15 mV max), 6× higher slew rate (17.8 V/μs vs. 3 V/μs), and lower 1/f noise (50 nV/√Hz at 10 Hz vs. 70 nV/√Hz). These differences allow TL052IP to replace TL082 directly in existing layouts while enabling higher closed-loop bandwidth, reduced calibration effort, and better low-frequency SNR in sensor interfaces.
What is the thermal resistance (θJA) of TL052IP in PDIP-8 package?
The TL052IP in PDIP-8 (P package) has a junction-to-ambient thermal resistance (θJA) of 85 °C/W, as specified in Section 4.2 of the SLOS178B datasheet. This value assumes standard JEDEC 2S2P board conditions. At 8.4 mA supply current and ±15 V operation, power dissipation is ~252 mW, resulting in ~21 °C junction-to-ambient rise above ambient-well within the 150 °C max TJ limit even at 70 °C ambient.
Can unused channels of TL052IP be left floating?
No. Unused amplifiers in TL052IP must not be left floating, as this can cause oscillation or excessive current draw. Per Section 5.1.2 of the datasheet, unused channels should be configured as grounded unity-gain followers: connect non-inverting input to ground, inverting input to output, and leave output unconnected except for its feedback path. This ensures stable biasing and prevents parasitic coupling into active channels.
