Product details
Overview
TLC27M7CPS from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 500 µV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and rail-to-rail output swing down to the negative rail. It operates from 3 V to 16 V supply over 0°C to 70°C and supports single-supply transducer interfacing in battery-powered instrumentation.
For engineers reviewing the TLC27M7CPS datasheet, TLC27M7CPS pinout, TLC27M7CPS application, or TLC27M7CPS equivalent, this page delivers verified electrical specs, package mapping, thermal performance data, and real-world design context for low-power precision analog signal conditioning.
Technical Context
The TLC27M7CPS implements a dual-channel CMOS op-amp architecture with silicon-gate LinCMOS process, delivering high input impedance (10¹² Ω typ), ultra-low input bias current (0.6 pA typ at 25°C), and latch-up immunity. Its input stage extends below the negative rail, enabling true single-supply operation without level-shifting circuitry.
It achieves 525 kHz unity-gain bandwidth and 0.40 V/µs slew rate at VDD = 5 V, with phase margin of 40° - optimized for stable closed-loop gain configurations in sensor front-ends and active filters. Input offset voltage drift is specified at 0.1 µV/month, including first 30 days.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 500 µV max at 25°C - enables high-accuracy DC-coupled amplification without external trimming |
| Supply Voltage Range | 3 V to 16 V - supports single-cell Li-ion (3.0–4.2 V) and industrial 12 V rails without regulation |
| Input Noise Density | 32 nV/√Hz at 1 kHz - suitable for low-level thermocouple and strain gauge signal amplification |
| Common-Mode Input Range | Extends to −0.2 V below GND at VDD = 5 V - allows direct sensing of signals referenced below ground |
| Output Voltage Swing | Includes negative rail (VOL ≤ 50 mV at IOL = 0) - simplifies interface with ADCs and logic inputs |
| Supply Current | 210–560 µA per amplifier at 25°C - enables multi-year battery life in remote monitoring nodes |
| ESD Protection | 2000 V HBM per MIL-STD-883C Method 3015.2 - reduces handling sensitivity during PCB assembly |
Pinout & Package
Package: Plastic DIP (P) - 14-pin through-hole, 0.300-inch wide body, industry-standard footprint for prototyping and legacy industrial control boards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output channel A - drives loads up to ±30 mA, rail-to-rail swing |
| 2 | IN− A | Inverting input for channel A - high-impedance node (10¹² Ω), sensitive to layout parasitics |
| 3 | IN+ A | Non-inverting input for channel A - accepts common-mode voltages down to −0.2 V |
| 4 | GND | Analog ground reference - must be star-connected to minimize noise coupling between channels |
| 5 | VCC | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 1 cm of pin |
| 6 | OUT B | Inverting amplifier output channel B - independent output, no crosstalk above 90 dB |
| 7 | IN− B | Inverting input for channel B - electrically isolated from channel A per datasheet test conditions |

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 |
|---|---|---|---|
| TLC27M7CP | Same die, plastic DIP-8 package - pin-compatible but single-channel; requires two units for dual functionality | Lacks second amplifier channel; increases board area and component count for dual-path designs | Select only when space constraints favor discrete channel placement or legacy DIP-8 footprints are mandated |
| OPA2333AIDR | Zero-drift architecture, 10 µV max offset, 0.1 µV/°C drift - superior DC accuracy but higher quiescent current (17 µA per amp) | Higher power consumption limits use in multi-year battery applications; better for lab-grade measurement systems | Choose OPA2333AIDR only when sub-10 µV offset and near-zero drift outweigh 80× higher supply current |
Compared with TLC27M7CP, the TLC27M7CPS saves board space and interconnect complexity via integrated dual-channel topology; versus OPA2333AIDR, it trades absolute DC precision for ultra-low power and proven reliability in cost-sensitive industrial deployments.

FAQ
What is the maximum operating temperature range for the TLC27M7CPS?
The TLC27M7CPS is characterized for operation from 0°C to 70°C, as indicated by its "C" suffix. Absolute maximum junction temperature is 150°C, but continuous operation beyond 70°C is not guaranteed per datasheet specifications. For extended temperature applications, consider the TLC27M7I (−40°C to 85°C) or TLC27M7M (−55°C to 125°C) variants instead of the TLC27M7CPS.
Does the TLC27M7CPS support true rail-to-rail input operation?
The TLC27M7CPS does not support rail-to-rail input - its common-mode input voltage range extends to −0.2 V below GND and up to VDD − 1.5 V at 5 V supply, per datasheet Section 4. However, it does provide rail-to-rail output swing (VOL ≤ 50 mV, VOH ≥ VDD − 0.1 V), making it suitable for single-supply systems where only the output must reach the rails - a key capability of the TLC27M7CPS.
Can the TLC27M7CPS drive capacitive loads directly?
The TLC27M7CPS is stable with capacitive loads up to 20 pF, as confirmed by phase margin measurements (40° at 25°C, VDD = 5 V). Driving larger capacitive loads (e.g., >100 pF cables or ADC input capacitance) requires isolation resistance (≥500 Ω) in series with the output to maintain stability. This limitation is documented in the "Operating Characteristics" section of the TLC27M7CPS datasheet and applies across all temperature grades.
Is the TLC27M7CPS pin-compatible with other devices in the TLC27Mx family?
Yes - the TLC27M7CPS shares identical pinout and package dimensions with all P-package variants in the TLC27Mx family (e.g., TLC27M2CP, TLC27M7CP), including the same 14-pin DIP layout. This allows direct substitution within the same grade (C-suffix) for different offset voltage bins (e.g., upgrading from TLC27M2CP to TLC27M7CPS) without PCB changes, provided thermal and layout margins accommodate the TLC27M7CPS's slightly higher unity-gain bandwidth.
What is the typical input bias current of the TLC27M7CPS at 85°C?
The typical input bias current of the TLC27M7CPS at 85°C is not specified - the C-suffix grade is only characterized from 0°C to 70°C. At 70°C, the datasheet specifies 40–600 pA (max). For operation at 85°C, refer to the I-suffix variant TLC27M7I, which is tested across −40°C to 85°C and shows 200–2000 pA max at that temperature. The TLC27M7CPS should not be operated beyond 70°C per its official rating.
