Product details
Overview
TLC27L2MDR from Texas Instruments is a precision dual CMOS operational amplifier designed for low-power, single-supply sensor signal conditioning in extended-temperature industrial and military systems. It delivers 10 mV max input offset voltage at 25°C, ultra-low 34 µA typical supply current (VDD = 5 V), and rail-to-rail output swing down to the negative rail - enabling direct interfacing with transmitters and battery-powered field instrumentation.
For engineers reviewing the TLC27L2MDR datasheet, TLC27L2MDR pinout, TLC27L2MDR application, or TLC27L2MDR equivalent, key selection criteria include its −55°C to +125°C military-grade temperature range, LinCMOS™ input impedance of 10¹² Ω, input common-mode range extending to GND, and compatibility with 4–16 V supplies in harsh environments.
Technical Context
The TLC27L2MDR uses Texas Instruments' silicon-gate LinCMOS™ process to achieve stable input offset voltage (10 mV max, 1.4 µV/°C drift over −55°C to +125°C) without metal-gate degradation. Its dual-amplifier architecture supports independent channel operation with matched DC performance across temperature extremes.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and a common-mode input range that includes the negative rail - critical for single-supply transducer front-ends where signals reference ground.
Key Specifications

|---|---|
| Input Offset Voltage (max) | 10 mV at 25°C; ensures ≤±5 mV error in 1× gain buffer or comparator applications at room temperature |
| Supply Current (typ) | 34 µA at VDD = 5 V, 25°C; enables multi-year battery life in remote sensor nodes |
| Input Impedance | 10¹² Ω typical; minimizes loading on high-impedance sources like piezoelectric sensors or pH electrodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2CDR | Commercial grade (0°C to 70°C), same 10 mV VIO, lower cost, no military qualification testing | Limited to indoor, non-critical industrial controls; not suitable for aerospace or extended-temperature field deployments | Select when ambient temperature stays within 0–70°C and MIL-STD-883 compliance is unnecessary |
| TLC27L2IDR | Industrial grade (−40°C to +85°C), same 10 mV VIO, qualified per AEC-Q200 but not MIL-PRF-38535 | Suitable for automotive engine bay or factory automation; lacks −55°C low-temp capability and radiation tolerance | Select for cost-sensitive industrial or automotive applications requiring wider temp range than commercial but less stringent than military |

FAQ
What is the maximum operating temperature range for the TLC27L2MDR?
The TLC27L2MDR is specified for continuous operation from −55°C to +125°C, meeting MIL-PRF-38535 requirements for military-grade extended-temperature performance. This range is validated across all electrical parameters in the official Texas Instruments datasheet SLOS052E, including input offset voltage, supply current, and common-mode input range - making it suitable for downhole, aerospace, and defense applications where thermal extremes are routine.
Does the TLC27L2MDR support single-supply operation with input signals referenced to ground?
Yes, the TLC27L2MDR supports true single-supply operation with inputs extending to the negative rail (GND). Its common-mode input voltage range includes 0 V at all temperatures (−55°C to +125°C), allowing direct connection of grounded sensors such as RTDs, thermistors, or bridge circuits without level-shifting components - a key enabler for simplified, low-cost sensor front-ends in field transmitters.
What is the typical supply current draw of the TLC27L2MDR at 5 V?
The TLC27L2MDR draws 34 µA typical supply current (two amplifiers) at VDD = 5 V and 25°C, with a maximum of 42 µA over the full −55°C to +125°C range. This ultra-low quiescent current enables multi-year operation from primary lithium batteries in wireless sensor nodes and portable instrumentation - confirmed in Section 5.12 of the TI SLOS052E datasheet.
Is the TLC27L2MDR pin-compatible with other variants in the TLC27Lx family?
Yes, the TLC27L2MDR uses the standard SOIC-8 (D) package and shares identical pinout with all TLC27Lx dual op amps, including TLC27L2CDR, TLC27L2IDR, TLC27L2ADR, and TLC27L7MDR. Pin functions - 1IN+, 1IN−, 1OUT, GND, 2IN+, 2IN−, 2OUT, VDD - are fully consistent across the family, enabling drop-in replacement for different offset voltage grades or temperature ranges without PCB redesign.
What packaging and compliance information applies to the TLC27L2MDR?
The TLC27L2MDR is supplied in an 8-pin SOIC (D) package, RoHS-compliant and halogen-free per TI's packaging standards. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), requires no dry-pack handling, and is qualified to MIL-PRF-38535 Class K for military applications - documentation verified in TI's official "Mechanical, Packaging, and Orderable Information" section (Section 10) of SLOS052E.
