Texas Instruments TLE2061CDR

Overview

TLE2061CDR from Texas Instruments is a single-channel FET-input operational amplifier with 1.1 MHz gain-bandwidth product, 120 µA typical supply current, and high-output-drive capability into 100 Ω loads. It operates from ±3.5 V to ±18 V supplies, delivers ±14.5 V output swing at ±15 V supply into 600 Ω, and is used in analog input modules for industrial control systems.

For engineers reviewing the TLE2061CDR datasheet, TLE2061CDR pinout, TLE2061CDR application, or TLE2061CDR equivalent, key selection criteria include its JFET-input low bias current (±10 pA), low 1/f noise (1.1 µV_PP, 0.1–10 Hz), 2.6 V/µs slew rate at ±15 V, and SOIC-8 packaging suitable for space-constrained signal conditioning stages.

Technical Context

The TLE2061CDR implements a JFET-input stage with on-chip Zener trimming for DC precision, enabling low input offset voltage (max 3 mV at 25°C) and ultra-low input bias current (±10 pA typ). Its architecture supports rail-to-rail output swing within 1.5 V of rails under light load and maintains stability with capacitive loads up to 100 pF.

It features a unity-gain bandwidth of 1.8 MHz (typical at ±5 V), phase margin of 58° (RL = 10 kΩ), and common-mode rejection ratio of 72 dB (min) at ±15 V - optimized for precision amplification in noisy industrial environments where high CMRR and supply rejection (kSVR ≥ 75 dB) are critical.

FAQ

What is the maximum operating temperature range for the TLE2061CDR?

The TLE2061CDR is rated for operation from 0°C to 70°C (commercial grade). This range is validated per TI's SLOS193D datasheet Section 5.2 and applies to all electrical characteristics unless otherwise noted. The device is not qualified for extended industrial (–40°C to 85°C) or military (–55°C to 125°C) temperature ranges - those require TLE2061I or TLE2061M variants respectively. Always verify ambient and junction temperature limits in your specific layout.

Does the TLE2061CDR support single-supply operation?

Yes, the TLE2061CDR supports single-supply operation up to +36 V (VCC+ to VCC−), as confirmed by Absolute Maximum Ratings in Section 5.1 of the datasheet. However, its input common-mode range does not extend to the negative rail - at ±5 V supply, VICR is –1.6 V to +4 V - so single-supply use requires appropriate biasing (e.g., mid-rail reference) to keep inputs within specification. Output swing remains asymmetric but usable down to ~1.5 V above VCC−.

What is the purpose of Pins 1 and 5 on the TLE2061CDR SOIC-8 package?

Pins 1 and 5 on the TLE2061CDR are designated as offset null terminals but are internally unconnected (NC) per the device's D-package configuration. Unlike earlier op-amps, the TLE2061CDR uses on-chip Zener trimming to achieve factory-set offset voltage, eliminating the need for external nulling circuitry. These pins must be left floating - no connection or pull-up/down is required or recommended in standard operation.

How does the TLE2061CDR's output drive capability compare to standard rail-to-rail op-amps?

The TLE2061CDR is not a rail-to-rail output (RRO) op-amp; its output swings to within ~1.5 V of each rail under load (e.g., ±12.5 V into 600 Ω at ±15 V supply). However, it uniquely specifies performance into low-impedance loads (100 Ω), delivering >20 mA continuous current - a capability most RRO op-amps lack. This makes TLE2061CDR better suited for driving ADC references, transmission lines, or active filters where both voltage headroom and current delivery matter.

Can the TLE2061CDR replace the TL071 in existing designs?

The TLE2061CDR can functionally replace the TL071 in many applications due to identical SOIC-8 pinout and similar AC performance, but key differences require validation: TLE2061CDR draws only 120 µA (vs. 1.4 mA), has lower input bias current (±10 pA vs. ±30 pA), and guarantees 100 Ω drive - advantages for low-power and low-Z systems. However, its 1.1 MHz GBW is lower than TL071's 3 MHz, so bandwidth-critical circuits (e.g., active filters above 100 kHz) may need redesign. Always re-characterize loop stability and settling time.
