Product details
Overview
TLC27L1ID from Texas Instruments is a low-power, single-supply operational amplifier using LinCMOS technology, featuring 10 mV max input offset voltage at 25°C, 68 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 over −40°C to +85°C and is used in battery-powered field transmitters for pressure, temperature, and level sensing.
For engineers reviewing the TLC27L1ID datasheet, TLC27L1ID pinout, TLC27L1ID application, or TLC27L1ID equivalent, key selection criteria include its ultra-low supply current (17 µA typ), high input impedance (10¹² Ω), wide common-mode input range extending below ground, and ESD protection rated to 2000 V per MIL-STD-883C.
Technical Context
The TLC27L1ID implements a silicon-gate LinCMOS input stage that delivers bipolar-like performance-such as high CMRR (87 dB typ) and supply voltage rejection (97 dB typ)-without the power penalty of bipolar op-amps. Its architecture supports single-supply operation with common-mode input voltage down to −0.2 V and output swing to the negative rail.
It features two legacy offset adjustment pins (OFFSET N1 and OFFSET N2), though these are NC on new silicon; functional operation requires no external trimming. The device exhibits stable unity-gain performance (phase margin ≥34°) with 20 pF capacitive load and supports bandwidths up to 110 kHz at VDD = 10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 16 V - enables direct use with 5 V, 9 V, or 12 V battery or industrial rails without regulation |
| Input Offset Voltage (max) | 10 mV at 25°C - sets baseline DC error in precision sensor signal conditioning |
| Supply Current (typ) | 17 µA at VDD = 5 V - supports multi-year operation in remote, low-duty-cycle sensor nodes |
| Input Noise Density | 68 nV/√Hz at f = 1 kHz - suitable for low-frequency transducer interfacing without dominant noise contribution |
| Common-Mode Input Range | −0.2 V to VDD − 1.5 V - allows direct connection to grounded sensors and single-supply biasing |
| Output Voltage Swing | Includes negative rail - simplifies level-shifting and eliminates need for dual supplies in analog front-ends |

Key Features
| Feature | Design Value |
|---|---|
| LinCMOS input stage | Delivers 10¹² Ω input impedance and sub-pA bias current - preserves signal integrity in high-Z sensor circuits |
| Rail-to-rail output swing | Drives to GND and within 1.1 V of VDD - maximizes dynamic range in 3.3 V or 5 V systems |
| Single-supply optimized design | Operates with VIC down to −0.2 V - eliminates need for level-shifting or negative supply in transmitter front-ends |
| Low-voltage, low-power operation | 17 µA supply current at 5 V - extends battery life in wireless field devices beyond 10 years at 1% duty cycle |
| Integrated ESD protection | 2000 V HBM rating - reduces BOM count by eliminating discrete TVS diodes in industrial I/O modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2ID | Dual-channel version in same SOIC-8 package; identical specs per channel except higher total IDD (34 µA typ) | Used where space-constrained designs require two matched amplifiers (e.g., instrumentation amp front-end) | Select when dual-channel functionality is needed without layout change - same footprint and thermal profile |
| TLV2461IDBVR | Lower offset (2 mV max), higher GBW (6.4 MHz), but higher supply current (550 µA typ) and narrower VDD range (2.7–6 V) | Suitable for higher-speed, higher-accuracy applications where battery life is secondary to precision | Choose for improved DC accuracy and bandwidth in 3.3 V systems; avoid in 12 V or ultra-low-power deployments |

FAQ
What is the maximum operating temperature range for the TLC27L1ID?
The TLC27L1ID is characterized for operation from −40°C to +85°C, meeting industrial temperature requirements. This rating applies across its full specified supply voltage range of 4 V to 16 V and is validated per the I-suffix specification in the official datasheet (SLOS154C). The device maintains key parameters-including input offset voltage (13 mV max over temperature), supply current (10–27 µA), and CMRR (60–85 dB)-within this range.
Does the TLC27L1ID support true single-supply operation with inputs referenced to ground?
Yes, the TLC27L1ID 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, allowing direct connection of grounded sensors or resistive bridges without level-shifting circuitry. This capability is enabled by its LinCMOS input stage and is explicitly verified in Section 5.3 (Recommended Operating Conditions) of the TLC27L1ID datasheet.
Are the OFFSET N1 and OFFSET N2 pins functional on the TLC27L1ID?
No, the OFFSET N1 (Pin 1) and OFFSET N2 (Pin 5) pins are not functional on modern production lots of the TLC27L1ID. As stated in Table 4-1 of the datasheet, these pins are "NC, non internally connected" on new silicon. They may be left floating or tied to GND for mechanical stability; no offset trimming is possible or required for standard operation.
What is the typical supply current of the TLC27L1ID at 5 V and 25°C?
The typical supply current of the TLC27L1ID is 17 µA at VDD = 5 V and TA = 25°C, as specified in Section 5.7 (Electrical Characteristics, I Suffix) of the datasheet. This value increases to 27 µA at −40°C and decreases to 13 µA at 85°C under the same conditions, reflecting its stable low-power behavior across temperature.
Can the TLC27L1ID drive a 1 MΩ load while maintaining rail-to-rail output swing?
Yes, the TLC27L1ID can drive a 1 MΩ load while maintaining rail-to-rail output swing. At VDD = 5 V and 25°C, its low-level output voltage (VOL) is specified at ≤50 mV with IOL = 0 mA and RL = 1 MΩ, and high-level output voltage (VOH) reaches ≥3 V. These values confirm full swing capability into high-impedance loads typical in sensor interface and data acquisition circuits.
