Product details
Overview
TLE2072CD from Texas Instruments is a dual JFET-input operational amplifier optimized for high-voltage, low-noise, and high-speed precision signal conditioning. It delivers ±19V supply operation, 10MHz unity-gain bandwidth, 32V/μs slew rate, and 17nV/√Hz input voltage noise at 1kHz - enabling accurate amplification in oscilloscope front-ends and electricity meter analog signal chains.
For engineers reviewing the TLE2072CD datasheet, TLE2072CD pinout, TLE2072CD application, or TLE2072CD equivalent, this device is selected where rail-to-rail input capability, low bias current (±15pA), and stable AC performance under ±15V operation are required - especially in test equipment, industrial energy measurement, and flight control analog interfaces.
Technical Context
The TLE2072CD uses Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, supporting differential input voltages up to the supply rails. Its unity-gain stability and 56° phase margin ensure robust closed-loop behavior without external compensation.
It operates across 0°C to 70°C ambient temperature with ±2.25V to ±19V supply range, delivering 1.35–2.48mA per channel quiescent current and maintaining CMRR ≥85dB and PSRR ≥82dB - critical for rejecting power supply ripple and common-mode interference in high-impedance sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2072ID | Wider operating temperature range (−40°C to 85°C) and tighter input offset voltage (3.5mV max vs. 6mV), same SOIC-8 package and pinout | Required for industrial environments with extended thermal cycling or higher reliability demands | Select TLE2072ID when ambient temperature exceeds 70°C or long-term offset stability is critical |
| TL072CP | Lower slew rate (13V/μs), higher input noise (18nV/√Hz), no guaranteed rail-to-rail input - same SOIC-8 footprint | Suitable only for cost-sensitive, lower-bandwidth applications where 10MHz bandwidth is not required | Choose TL072CP only if design tolerates reduced speed, higher noise, and limited common-mode range |
Compared with TLE2072ID, the TLE2072CD offers lower cost and sufficient performance for commercial-grade test equipment and energy meters; versus TL072CP, it provides measurable improvements in bandwidth, noise, and input voltage range - justifying its use where signal fidelity is prioritized over BOM cost alone.

FAQ
What is the maximum supply voltage rating for the TLE2072CD?
The TLE2072CD supports a total supply voltage (V+ to V−) of up to 38V, corresponding to ±19V operation. This is confirmed in the Absolute Maximum Ratings table of the official datasheet (SLOS181D), where VCC+ is rated from 0V to 38V relative to VCC−. Operation beyond this risks permanent damage, and recommended conditions limit continuous use to ±19V.
Does the TLE2072CD support rail-to-rail input operation?
Yes, the TLE2072CD accepts common-mode input voltages extending to within 0.9V of the supply rails at ±5V operation and to within 10.9V at ±15V operation - explicitly stated in the Recommended Operating Conditions table. This rail-to-rail input capability allows direct interfacing with sensors referenced to V+ or V− without external level-shifting circuitry.
What is the typical input bias current specification for the TLE2072CD?
The typical input bias current for the TLE2072CD is ±15pA at 25°C, with a maximum of ±175pA over the full 0°C to 70°C operating range. This value is documented in Section 6.3 (TLE2072C Electrical Characteristics) of the datasheet and reflects the JFET-input architecture's ultra-low leakage - critical for high-impedance sensor interfaces.
Is the TLE2072CD unity-gain stable?
Yes, the TLE2072CD is unity-gain stable, with a measured phase margin of 56° at unity gain (Section 6.4). Its 10.6MHz unity-gain bandwidth and stable step response (0.25μs settling to 10mV for a 2V step) confirm unconditional stability in gain-of-1 configurations without external compensation components.
What package type is used for the TLE2072CD?
The TLE2072CD is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package designated "D", measuring 4.9mm × 6mm. This surface-mount package is tape-and-reel compatible and matches industry-standard footprints for automated assembly - confirmed in Table 4-2 and Section 10 of the TLE207x datasheet (SLOS181D).
