Product details
Overview
TLE2072IP from Texas Instruments is a dual JFET-input operational amplifier optimized for high-voltage, low-noise, and high-speed precision applications. It delivers ±19V supply operation, 10MHz unity-gain bandwidth, 32V/μs slew rate, and 17nV/√Hz input voltage noise at 1kHz - enabling accurate signal conditioning in oscilloscopes, electricity meters, and flight control units.
For engineers reviewing the TLE2072IP datasheet, TLE2072IP pinout, TLE2072IP application, or TLE2072IP equivalent, key selection criteria include its −40°C to +85°C industrial temperature range, PDIP-8 package, low 15pA input bias current, rail-to-rail input capability, and compatibility with ±2.25V to ±19V supplies in dual-channel configurations.
Technical Context
The TLE2072IP uses JFET-input transistors with on-chip Zener trimming for DC precision, supporting differential inputs up to the supply rails and delivering stable unity-gain performance. Its architecture balances wide dynamic range (±19V) with low 17nV/√Hz noise floor and high 32V/μs slew rate for fast transient response.
It operates across ±2.25V to ±19V supplies with common-mode input range extending to within 0.9V of rails (at ±5V) or −10.8V to +15V (at ±15V), and maintains 10.6MHz unity-gain bandwidth and 56° phase margin under 2kΩ load with 25pF capacitive load.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CP | Higher 25nV/√Hz noise, 3mV VIO max, same PDIP-8 package and pinout | Limited to ±18V supply; lower slew rate (13V/μs) restricts use in >1MHz signal paths | Select TL072CP only for cost-sensitive, non-critical AC-coupled audio or general-purpose analog where noise <17nV/√Hz is not required |
| OPA2134PA | Lower 8nV/√Hz noise, 10MHz GBW, SO-8 package only - no PDIP-8 option | Requires PCB redesign for surface-mount assembly; superior THD+N (0.00008%) benefits audio-grade designs | Choose OPA2134PA when board space permits SMT and ultra-low distortion is mandatory, but avoid if through-hole manufacturing is fixed |
Compared with TL072CP and OPA2134PA, the TLE2072IP uniquely combines PDIP-8 compatibility, ±19V operation, and 17nV/√Hz noise - making it the only drop-in replacement for legacy industrial designs requiring extended supply range without sacrificing noise performance.

FAQ
What is the maximum supply voltage rating for the TLE2072IP?
The TLE2072IP supports a maximum total supply voltage of 38V, meaning it can operate with ±19V supplies or asymmetric rails up to +19V and −19V. This rating is confirmed in Section 6.1 Absolute Maximum Ratings of the TI datasheet (SLOS181D), and exceeds standard ±15V op-amps to accommodate high-dynamic-range industrial signal conditioning. The TLE2072IP maintains specified performance across this full range.
Does the TLE2072IP support rail-to-rail input operation?
Yes, the TLE2072IP allows differential inputs to swing up to the supply rails - specifically, its common-mode input voltage range extends to within 0.8V of V+ and V− at ±15V supplies (e.g., −10.8V to +15V). This rail-to-rail input capability is explicitly stated in the "Features" section and verified in Table 6.2 Recommended Operating Conditions. It eliminates the need for external level-shifting in many sensor interface applications.
What is the guaranteed input offset voltage specification for TLE2072IP over temperature?
The TLE2072IP has a maximum input offset voltage of 6mV over its full operating temperature range of −40°C to +85°C, as specified in Table 4-2 (TLE2072 Available Options) and confirmed in Section 6.7 Electrical Characteristics for the 'I' grade. This is higher than the 3.5mV typical spec for the 'A' variant but remains tightly bounded for industrial-grade precision requirements.
Can the TLE2072IP drive a 600Ω load effectively?
Yes, the TLE2072IP delivers ±65mA short-circuit output current and maintains large-signal voltage gain >80dB into 600Ω loads (Section 6.3), supporting robust driving of coaxial cables, legacy instrumentation inputs, and low-impedance filters. At ±15V supply, its output swing reaches ±13.5V into 2mA load - confirming ample headroom for 600Ω termination without clipping.
Is the TLE2072IP unity-gain stable, and what is its phase margin?
Yes, the TLE2072IP is unity-gain stable with a measured phase margin of 56° at unity gain under 2kΩ load and 25pF capacitive load (Section 6.4 Operating Characteristics). This stability is inherent to its internal compensation and requires no external components - enabling reliable use in buffers, active filters, and gain-of-one configurations without risk of oscillation.
