Texas Instruments TLC27M2ACDRG4

Overview

TLC27M2ACDRG4 from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 5 mV max input offset voltage at 25°C, rail-to-rail output swing (includes negative rail), and operation from 3 V to 16 V supply across 0°C to 70°C. It delivers 0.4 V/µs slew rate, 32 nV/√Hz input noise at 1 kHz, and 525 kHz unity-gain bandwidth - ideal for low-power sensor signal conditioning in portable instrumentation.

For engineers reviewing the TLC27M2ACDRG4 datasheet, TLC27M2ACDRG4 pinout, TLC27M2ACDRG4 application, or TLC27M2ACDRG4 equivalent, key selection criteria include its trimmed offset grade (A-suffix), SOIC-8 packaging, single-supply capability down to 3 V, high CMRR (91 dB), and ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2.

Technical Context

The TLC27M2ACDRG4 implements silicon-gate LinCMOS process technology to achieve stable offset voltage with minimal drift (1.7 µV/°C over 25°C–70°C) and ultra-low input bias current (0.6 pA typ at 25°C). Its architecture supports common-mode input voltage extending below the negative rail, enabling true single-supply transducer interfacing without level-shifting circuitry.

It integrates internal ESD-protection diodes and latch-up immunity, with absolute maximum ratings including ±30 mA output current per amplifier and 18 V supply voltage. The device exhibits robust phase margin (40° at 25°C, 39° at 70°C) under 20 pF capacitive load, supporting stable unity-gain configurations in active filter and buffer designs.

FAQ

What is the maximum input offset voltage specification for TLC27M2ACDRG4?

The TLC27M2ACDRG4 has a maximum input offset voltage of 5 mV at 25°C and 6.5 mV across the full 0°C to 70°C operating range. This A-grade specification is confirmed in the Electrical Characteristics tables for VDD = 5 V and VDD = 10 V, under both C-suffix (0°C to 70°C) and I-suffix conditions. The value reflects factory-trimmed performance, distinguishing it from the standard TLC27M2C (10 mV max) and high-precision TLC27M7C (500 µV max).

Does TLC27M2ACDRG4 support true single-supply operation with inputs referenced to ground?

Yes, the TLC27M2ACDRG4 supports true single-supply operation with inputs referenced to ground. Its common-mode input voltage range extends to −0.2 V (below GND) at VDD = 5 V, and its output swings fully to the negative rail (0 V). This capability is explicitly documented in the Recommended Operating Conditions table and enables direct interfacing with ground-referenced sensors such as thermistors or bridge transducers without level-shifting circuitry.

What is the supply current consumption of TLC27M2ACDRG4 at 5 V operation?

The TLC27M2ACDRG4 draws 210 µA to 560 µA supply current (IDD) for both amplifiers combined, measured at VDD = 5 V, VO = 2.5 V, no load, and VIC = 2.5 V. Typical consumption is 370 µA at 25°C, rising to 560 µA at 0°C and falling to 210 µA at 70°C. This low quiescent current supports multi-year battery life in always-on sensor nodes, and is consistent across all TLC27M2x variants regardless of offset grade.

Is TLC27M2ACDRG4 pin-compatible with other devices in the TLC27M2 family?

Yes, the TLC27M2ACDRG4 is pin-compatible with all SOIC-8 packaged members of the TLC27M2 family, including TLC27M2CDR, TLC27M2BCDR, and TLC27M2CDRG4. All share identical D-package pinout (1OUT, 1IN−, 1IN+, GND, 2IN+, 2IN−, 2OUT, VCC), allowing drop-in replacement based on required offset voltage grade without PCB modification. This compatibility is confirmed in the "Available Options" table and package drawings in the datasheet.

What packaging and reel specifications apply to TLC27M2ACDRG4?

The TLC27M2ACDRG4 is supplied in an SOIC-8 (D) package, 150 mil width, with tape-and-reel packaging indicated by the "R" and "G4" suffixes. Per TI's Package Option Addendum, it ships in 2500-unit reels (standard quantity for D package), with moisture sensitivity level (MSL) rating appropriate for standard SMT assembly. The "G4" suffix denotes green (lead-free) RoHS-compliant finish, and the device is rated for reflow per JEDEC J-STD-020.
