Product details
Overview
TLC27M7IP from Texas Instruments is a dual precision LinCMOS operational amplifier optimized for single-supply operation, 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 4 V to 16 V across −40°C to +85°C and delivers 0.4 V/µs slew rate and 525 kHz unity-gain bandwidth at VDD = 5 V - ideal for low-power sensor signal conditioning in industrial monitoring systems.
For engineers reviewing the TLC27M7IP datasheet, TLC27M7IP pinout, TLC27M7IP application, or TLC27M7IP equivalent, key selection criteria include its trimmed offset voltage grade, extended common-mode input range below ground (C- and I-suffix types), low quiescent current (210–560 µA per amplifier), ESD protection up to 2000 V, and compatibility with battery-powered remote instrumentation requiring stable DC accuracy over temperature.
Technical Context
The TLC27M7IP uses silicon-gate LinCMOS process technology to achieve far superior input offset voltage stability versus metal-gate alternatives, with typical drift of only 0.1 µV/month including first 30 days. Its high input impedance (10¹² Ω typ) and ultra-low input bias current (0.6 pA typ at 25°C) enable high-impedance source interfacing without significant error.
Designed for single-supply use, it supports common-mode input voltage down to −0.2 V (at VDD = 5 V) and output swing to within 50 mV of GND. Internal ESD-protection circuitry meets MIL-STD-883C Method 3015.2 (2000 V), and latch-up immunity is built-in per design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 500 µV max at 25°C - enables high-accuracy DC amplification without external trimming in precision transducer interfaces. |
| Supply Voltage Range | 4 V to 16 V - supports wide-input industrial power rails and battery-backed operation from 4-cell alkaline or Li-ion configurations. |
| Operating Temperature | −40°C to +85°C - qualified for automotive under-hood, factory automation, and outdoor environmental sensing applications. |
| Input Noise Density | 32 nV/√Hz at 1 kHz - ensures minimal added noise in low-level analog front-ends such as strain gauge or thermopile amplifiers. |
| Slew Rate | 0.4 V/µs at VDD = 5 V - sufficient for <10 kHz small-signal bandwidth in unity-gain buffers and active filters. |
| Unity-Gain Bandwidth | 525 kHz at VDD = 5 V - allows stable closed-loop gain configurations up to ~10× with adequate phase margin (>38°). |
| Supply Current | 210–560 µA per amplifier - enables multi-channel low-power designs with total system supply current under 1.2 mA. |
Pinout & Package
Package: 8-pin plastic DIP (P package), through-hole mounting, 0.3-inch width, JEDEC MS-001 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads up to ±30 mA; swings to within 50 mV of GND and 1.1 V below VDD. |
| 2 | IN− A | Inverting input - high-impedance node (10¹² Ω); accepts signals down to −0.2 V relative to GND. |
| 3 | IN+ A | Non-inverting input - identical electrical characteristics to IN− A; used for differential or single-ended configurations. |
| 4 | GND | Analog ground reference - must be low-impedance; shared return for both amplifiers and supply decoupling. |
| 5 | VCC | Positive supply rail - accepts 4–16 V; requires local 0.1 µF ceramic decoupling capacitor to GND. |
| 6 | OUT B | Second amplifier output - independent channel; same drive capability and rail-swing behavior as OUT A. |
| 7 | IN− B | Inverting input for second amplifier - electrically isolated from Channel A; supports dual independent signal paths. |
| 8 | IN+ B | Non-inverting input for second amplifier - matches IN+ A performance; enables dual-channel instrumentation or filtering. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing to GND | Enables true single-supply operation with zero-output capability - eliminates need for negative supply in portable sensors. |
| Trimmed input offset voltage (500 µV max) | Reduces DC error accumulation in multi-stage amplifiers and improves accuracy in 12-bit ADC front-ends without calibration. |
| Ultra-low input bias current (0.6 pA typ) | Preserves signal integrity when driving from high-impedance sources like pH electrodes or piezoelectric sensors. |
| ESD protection (2000 V HBM) | Allows safe handling and board-level assembly without special ESD precautions beyond standard IPC-610 practices. |
| Latch-up immunity | Prevents destructive failure during transient overvoltage events on inputs or outputs - critical for field-deployed equipment. |
Applications
| Industrial Sensor Signal Conditioning | Portable Battery-Powered Instrumentation |

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 |
|---|---|---|---|
| TLV2772IP | Higher speed (2 MHz GBW), lower VIO (250 µV max), but higher supply current (1.3 mA/ch) and narrower temp range (−40°C to +125°C not supported). | Better for higher-bandwidth active filters; unsuitable for ultra-low-power battery systems due to 6× higher IDD. | Select TLV2772IP only when bandwidth >1 MHz is required and power budget allows ≥2.6 mA total. |
| OPA2333PA | Zero-drift architecture, 2 µV max VIO, 0.02 µV/°C drift, but higher cost and 17 µA supply current per channel. | Required for sub-µV DC stability over temperature; overqualified for applications where 500 µV VIO is acceptable. | Choose OPA2333PA only for medical-grade DC accuracy; TLC27M7IP remains optimal for cost-sensitive industrial designs. |
Compared with TLV2772IP and OPA2333PA, the TLC27M7IP offers the best balance of precision (500 µV VIO), ultra-low power (210 µA/ch), and wide temperature support (−40°C to +85°C) in a legacy-compatible DIP package - making it uniquely suited for long-lifecycle industrial retrofits and cost-constrained embedded systems.

FAQ
What is the maximum input offset voltage specification for TLC27M7IP at 25°C?
The maximum input offset voltage for TLC27M7IP at 25°C is 500 µV, as specified in the "Available Options" table and confirmed in the electrical characteristics section for I-suffix devices at VDD = 5 V. This value applies across the full −40°C to +85°C operating range, with typical drift of 0.1 µV/month including the first 30 days.
Does TLC27M7IP support true single-supply operation with input signals below ground?
Yes, TLC27M7IP supports true single-supply operation with common-mode input voltage extending to −0.2 V (at VDD = 5 V), verified in the recommended operating conditions table. This capability is explicitly enabled for C- and I-suffix variants like TLC27M7IP and allows direct interfacing with sensors whose outputs swing slightly below GND without level-shifting circuitry.
What is the supply current consumption of TLC27M7IP at 25°C and VDD = 5 V?
At 25°C and VDD = 5 V, the supply current for TLC27M7IP is specified as 210 µA (minimum), 370 µA (typical), and 560 µA (maximum) for both amplifiers combined - i.e., 105–280 µA per channel. This low IDD enables multi-channel designs with total quiescent current under 1.2 mA, critical for battery longevity.
Is TLC27M7IP pin-compatible with other devices in the TLC27Mx family?
Yes, TLC27M7IP shares identical 8-pin DIP (P) package pinout and footprint with all P-package variants in the TLC27Mx family, including TLC27M2IP, TLC27M2AIP, and TLC27M2BIP. Pin functions (OUT A, IN− A, IN+ A, GND, VCC, OUT B, IN− B, IN+ B) are fully consistent across these parts, enabling drop-in replacement within the same offset voltage grade and temperature range.
What packaging options are available for TLC27M7IP besides the P package?
TLC27M7IP is exclusively offered in the 8-pin plastic DIP (P) package, as confirmed in the "AVAILABLE OPTIONS" table where only "TLC27M7IP" appears under the P column for the −40°C to +85°C temperature grade. Other variants like TLC27M7ID (SOIC) and TLC27M7MP (ceramic DIP) exist, but TLC27M7IP is P-package only - no SOIC, TSSOP, or chip-carrier versions are assigned to this specific part number.
