Product details
Overview
TLE2061CP from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for high-voltage (±18 V), low-power (120 μA typical supply current), and high-output-drive applications. It delivers 1.1 MHz gain-bandwidth product, ±14.9 V output swing into 10 kΩ at ±15 V supply, and 43 nV/√Hz input voltage noise at 1 kHz - enabling precision signal conditioning in engine control units and analog input modules.
For engineers reviewing the TLE2061CP datasheet, TLE2061CP pinout, TLE2061CP application, or TLE2061CP equivalent, key selection criteria include its FET-input architecture for ultra-low input bias current (±10 pA typ), specified drive into 100 Ω loads, 3.1 mV max input offset voltage (C-grade), and PDIP-8 packaging suitable for industrial temperature range (0°C to 70°C).
Technical Context
The TLE2061CP uses a JFET-input stage with on-chip Zener trimming for DC precision, supporting rail-to-rail common-mode input range (–11 V to +13 V at ±15 V supply) and delivering 2.6 V/μs slew rate. Its open-loop output impedance is 575 Ω, and phase margin is 46° at unity gain with 10 kΩ load and 100 pF capacitance.
It operates across ±3.5 V to ±18 V dual supplies, exhibits 72 dB CMRR and 75 dB PSRR at ±15 V, and maintains stable operation with capacitive loads up to 100 pF - making it suitable for closed-loop sensor interfaces and active filtering where low quiescent current and high-voltage headroom are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±3.5 V to ±18 V - supports wide industrial and automotive battery-derived rails without level-shifting. |
| Gain-Bandwidth Product | 1.1 MHz - enables stable unity-gain buffer or 10× gain amplification up to ~110 kHz. |
| Input Offset Voltage (max) | 3.1 mV at 25°C (C-grade) - ensures ≤3.1 mV DC error in precision DC-coupled signal paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2061CD | Same electrical specs, SOIC-8 package (4.9 mm × 6 mm) - surface-mount compatible, no through-hole footprint. | Preferred for automated SMT assembly; thermal resistance differs (SOIC has higher θJA than PDIP). | Select when board space is constrained and reflow soldering is used; verify layout thermal relief for 120 μA operation. |
| TL071CP | Lower GBW (3 MHz), higher supply current (1.4 mA), same PDIP-8 package - not μPower, but wider bandwidth. | Better for AC-coupled audio or higher-speed signal paths where quiescent power is secondary. | Choose only if bandwidth >1.1 MHz is required and 12× higher supply current is acceptable. |
Compared with TLE2061CD and TL071CP, the TLE2061CP uniquely balances ultra-low power (120 μA), high-voltage operation (±18 V), and FET-input precision in a through-hole package - making it irreplaceable for legacy industrial designs requiring manual assembly or socketing.

FAQ
What is the maximum operating temperature range for the TLE2061CP?
The TLE2061CP is rated for 0°C to 70°C free-air operating temperature (C-suffix grade). This range is validated per TI's SLOS193D datasheet Section 5.2 and applies to all electrical characteristics unless otherwise noted. Operation outside this range may cause parametric shift or reliability degradation; for extended temperature use, consider the TLE2061IP (–40°C to +85°C) or TLE2061M (–55°C to +125°C) variants.
Does the TLE2061CP support rail-to-rail input or output?
The TLE2061CP does not provide rail-to-rail input or output. Its common-mode input range is –11 V to +13 V at ±15 V supply (Section 5.2), and output swing is ±14.9 V into 10 kΩ - approximately 100 mV from each rail. It cannot accept inputs at VCC− or VCC+, nor drive outputs fully to either supply. For true rail-to-rail operation, alternative families like TLV2461 or OPA333 should be evaluated.
Can the TLE2061CP drive a 600 Ω load effectively?
Yes - the TLE2061CP is explicitly characterized into 600 Ω loads in its datasheet (Section 5.5, VOM± specifications at ±15 V). It delivers ±12.5 V minimum output swing under those conditions, confirming usable drive capability for legacy line-driver or instrumentation amplifier applications. However, output current exceeds 20 mA, so thermal derating and PCB copper area must be verified per application.
What is the input offset voltage specification for the TLE2061CP at 25°C?
The TLE2061CP has a maximum input offset voltage of 3.1 mV at 25°C (Section 5.3, TLE2061C column). This value is guaranteed for the C-grade part and represents worst-case DC error before trimming. Typical offset is 0.1 mV, and temperature coefficient is 1 μV/°C - meaning total drift remains under ±0.1 mV over the 0°C to 70°C range.
Is the TLE2061CP pin-compatible with other TLE206x variants?
Yes - all TLE206x single-amplifier variants (TLE2061, TLE2061A, TLE2061B, TLE2061M, etc.) share identical PDIP-8 and SOIC-8 pinouts per Figures 4-1 and 4-2 in the datasheet. Pin 1 (NC), Pin 2 (IN−), Pin 3 (IN+), Pin 4 (VCC−), Pin 5 (NC), Pin 6 (OUT), Pin 7 (VCC+), and Pin 8 (NC) are functionally identical across the family, enabling direct substitution where electrical specs align.
