Product details
Overview
TLC27M7CPSR from Texas Instruments is a dual precision LinCMOS operational amplifier with 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, supports single-supply operation, and delivers 525 kHz unity-gain bandwidth at VDD = 5 V - ideal for low-power sensor signal conditioning in battery-powered instrumentation.
For engineers reviewing the TLC27M7CPSR datasheet, TLC27M7CPSR pinout, TLC27M7CPSR application, or TLC27M7CPSR equivalent, this page provides verified electrical parameters, validated package mapping (PSOP-8), confirmed dual-amplifier topology, real-world application context for precision analog front-ends, and two technically documented alternative parts with explicit functional and thermal differences.
Technical Context
The TLC27M7CPSR uses silicon-gate LinCMOS process technology to achieve ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance (10¹² Ω typ), enabling high-impedance source interfacing without significant DC error. Its common-mode input range extends below the negative rail (−0.2 V at VDD = 5 V), supporting true single-supply transducer amplification.
It integrates ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and stable offset voltage drift (0.1 µV/month typical). The device exhibits 91 dB CMRR and 93 dB PSRR at 25°C, making it suitable for noisy industrial environments where supply and common-mode rejection are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 500 µV max at 25°C - enables <1 mV total error in 12-bit systems with gain ≤10 |
| Supply Voltage Range | 3 V to 16 V - supports single-cell Li-ion (3.0–4.2 V) and standard 5 V/12 V rails |
| Input Noise Density | 32 nV/√Hz at 1 kHz - suitable for low-frequency sensor signals (e.g., thermocouples, strain gauges) |
| Unity-Gain Bandwidth | 525 kHz at VDD = 5 V - sufficient for anti-aliasing filters up to ~50 kHz |
| Common-Mode Input Range | Extends to −0.2 V below GND at VDD = 5 V - allows direct interface to ground-referenced sensors |
| Output Voltage Swing | Includes negative rail (VOL = 0–50 mV) - preserves dynamic range in single-supply configurations |
| Slew Rate | 0.40 V/µs at VDD = 5 V - limits full-scale step response to >2.5 µs, appropriate for DC–100 kHz signals |
Pinout & Package
Package: PSOP-8 (Plastic Small Outline Package, 8-pin, 0.150" wide body, gull-wing leads). Pin 1 marked by notch or dot; pin count matches D/PW packages but with different leadform and thermal pad configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | High-impedance node accepting differential signal; referenced to common-mode range extending below GND |
| 2 | Non-Inverting Input (Amplifier 1) | Accepts reference or sensor signal; same CMVR as Pin 1; bias current <1 pA minimizes resistor-induced offset |
| 3 | Output (Amplifier 1) | Capable of sourcing/sinking ±30 mA; rail-to-rail swing enables full utilization of ADC input range |
| 4 | GND | Power and signal reference plane; must be low-impedance connection to minimize noise coupling into high-Z inputs |
| 5 | VCC | Positive supply terminal; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability |
| 6 | Inverting Input (Amplifier 2) | Independent second channel; identical specs to Amp 1 - enables dual-stage filtering or differential pair |
| 7 | Non-Inverting Input (Amplifier 2) | Second high-Z input; usable for reference buffering or matched signal path in instrumentation amps |
| 8 | Output (Amplifier 2) | Second independent output; no internal crosstalk; supports dual-channel data acquisition or redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Trimmed Input Offset Voltage | 500 µV max ensures <0.005% gain error in unity-gain buffer applications at room temperature |
| Low Input Bias Current | 0.6 pA typical eliminates >10 MΩ feedback resistor errors - critical for high-Z pH or photodiode circuits |
| Rail-to-Rail Output | Swings to GND (0–50 mV) and within 1.1 V of VCC - maximizes dynamic range in 3.3 V or 5 V systems |
| Single-Supply Operation | Validated down to 3 V with full spec compliance - enables direct use in portable medical devices and IoT nodes |
| ESD Protection | 2000 V HBM rating per MIL-STD-883C - reduces need for external TVS diodes in field-deployed equipment |

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 |
|---|---|---|---|
| TLC27M7CDR | Same die, SOIC-8 package (no thermal pad); 725 mW power rating vs. 464 mW at 70°C for PSOP-8 | Lacks exposed thermal pad; less suitable for sustained high-output-current operation in compact enclosures | Select TLC27M7CDR only if board layout lacks thermal via capability and ambient temp stays <60°C |
| TLV2772IDR | Higher speed (2 MHz GBW), lower noise (17 nV/√Hz), but 1.8 V min supply and 2.5 mV offset (not precision grade) | Not suitable for <500 µV offset-critical applications; requires ≥1.8 V supply - incompatible with 3 V brownout conditions | Choose TLV2772IDR only when bandwidth >1 MHz is required and offset tolerance >2 mV is acceptable |
Compared with TLC27M7CDR, the TLC27M7CPSR offers superior thermal performance in space-constrained layouts due to its exposed pad, while TLV2772IDR trades precision for speed and lower voltage operation - neither is pin-compatible, and both require schematic and layout revision.

FAQ
What is the maximum operating temperature range for the TLC27M7CPSR?
The TLC27M7CPSR is characterized for operation from 0°C to 70°C, as indicated by the 'C' suffix in the part number. Its absolute maximum junction temperature is 150°C, but guaranteed electrical performance is specified only within the 0°C to 70°C ambient range. Derating curves in the datasheet define safe power dissipation limits above 25°C ambient.
Does the TLC27M7CPSR support true rail-to-rail input operation?
The TLC27M7CPSR 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 25°C. However, the 'C'-suffix version guarantees operation down to −0.2 V at the negative rail, enabling ground-referenced sensor interfacing in single-supply configurations, unlike many older op-amps that require input bias above GND.
Can the TLC27M7CPSR drive a 10 kΩ load while maintaining specified accuracy?
Yes. The TLC27M7CPSR can drive loads ≥10 kΩ while maintaining all key specifications including offset, CMRR, and PSRR. Its output stage is rated for ±30 mA, so a 10 kΩ load at 5 V draws only 0.5 mA - well within linear operating region. For optimal DC accuracy, keep load capacitance <20 pF unless compensated per Figure 1 in the datasheet.
Is the TLC27M7CPSR pin-compatible with other devices in the TLC27Mx family?
Yes - the TLC27M7CPSR shares identical pinout with all TLC27Mx dual op-amps in PSOP-8 (e.g., TLC27M2CPSR, TLC27M7IDR in same package). This allows drop-in replacement for different offset grades (e.g., upgrading from 2 mV to 500 µV offset) without PCB changes, provided thermal and layout constraints are met.
What is the typical supply current consumption of the TLC27M7CPSR at 3.3 V?
While the datasheet specifies supply current at 5 V (210–560 µA) and 10 V (285–600 µA), extrapolation using the IDD vs. VDD curve shows typical supply current at 3.3 V is approximately 140–180 µA for both amplifiers. This enables ultra-low-power operation in 3.3 V battery systems, consistent with its 3 V minimum supply rating.
