Product details
Overview
TLC27L4BIN from Texas Instruments is a precision quad operational amplifier in PDIP-14 package, optimized for single-supply operation with rail-to-rail output swing, 10 mV max input offset voltage at 25°C, ultra-low 195 µW quiescent power at 5 V, and common-mode input range extending below ground (–0.2 V). It serves as a low-power signal conditioning front-end in battery-powered sensor transmitters.
For engineers reviewing the TLC27L4BIN datasheet, TLC27L4BIN pinout, TLC27L4BIN application, or TLC27L4BIN equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial sensing use cases, and two technically documented alternative op-amps with explicit functional and parametric distinctions.
Technical Context
The TLC27L4BIN uses TI's LinCMOS™ silicon-gate process to achieve high input impedance (10¹² Ω typical), sub-picoamp input bias current (0.6 pA typ at 25°C), and latch-up immunity-enabling stable DC-coupled amplification in high-impedance sensor interfaces. Its input stage supports single-supply operation down to 3 V with common-mode range extending 0.2 V below GND.
It delivers 85 kHz unity-gain bandwidth and 0.03 V/µs slew rate at 5 V supply, with CMRR ≥65 dB and PSRR ≥70 dB across –40°C to +85°C. ESD protection meets MIL-STD-883C, Method 3015.2 (2000 V HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max 10 mV at 25°C - enables accurate DC amplification without frequent nulling in low-gain sensor buffers |
| Supply Current (4 amps) | 68 µA max at 25°C, 5 V - supports multi-year battery life in remote field transmitters |
| Common-Mode Input Range | –0.2 V to 3.5 V at 5 V supply - allows direct interfacing with grounded sensors and single-supply ADC drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L4CDR | SOIC-14 package, same electrical specs, rated 0°C to 70°C only | Suitable for cost-sensitive PCBs where surface-mount assembly is preferred and ambient stays above 0°C | Select when board space is constrained and thermal environment is commercial-grade |
| TLV2464IPW | Higher drive capability (±35 mA), rail-to-rail I/O, 230 µA supply current, 6 MHz GBW | Better for higher-speed or higher-load applications but consumes >3× more power than TLC27L4BIN | Choose when bandwidth >100 kHz or output current >30 mA is required, accepting reduced battery life |
Compared with TLC27L4CDR, the TLC27L4BIN offers through-hole reliability and extended –40°C operation but requires larger PCB real estate; versus TLV2464IPW, it trades bandwidth and output drive for 3.4× lower quiescent power and superior DC precision in low-speed sensor interfaces.

FAQ
What is the maximum operating temperature range for the TLC27L4BIN?
The TLC27L4BIN is characterized for operation from –40°C to +85°C, matching the I-suffix grade specified in the official TI datasheet SLOS053E. This extended temperature range makes the TLC27L4BIN suitable for industrial field transmitters deployed in uncontrolled ambient environments, unlike the C-suffix variants limited to 0°C–70°C.
Does the TLC27L4BIN support true rail-to-rail input operation?
No-the TLC27L4BIN supports rail-to-rail *output* swing but its common-mode input voltage range extends only to –0.2 V (below GND) and up to 3.5 V (at 5 V supply), not to VDD. This "beyond-the-rail" negative input capability enables direct interfacing with grounded sensors, but positive input headroom remains limited relative to VDD.
What is the typical input bias current of the TLC27L4BIN at room temperature?
The typical input bias current of the TLC27L4BIN is 0.6 pA at 25°C, as specified in Section 5.4 of the TI datasheet SLOS053E. This ultra-low value results from LinCMOS™ process technology and is critical for preserving signal integrity in high-impedance sensor circuits such as thermistor networks or piezoelectric transducers.
Can the TLC27L4BIN operate from a 3 V supply?
Yes-the TLC27L4BIN supports 3 V single-supply operation per Recommended Operating Conditions (Section 5.3), but only for the C-suffix grade (0°C–70°C). The I-suffix TLC27L4BIN requires a minimum 4 V supply across its full –40°C to +85°C range. Always verify supply voltage against temperature grade per datasheet Table 5.3.
Is the TLC27L4BIN pin-compatible with other TLC27Lx variants?
Yes-all TLC27Lx quad op-amps (including TLC27L4BIN, TLC27L4CDR, TLC27L4AIP, etc.) share identical 14-pin PDIP, SOIC, SOP, and TSSOP footprints and pinouts per Figure 4-1 and Table 4-1 in the datasheet. This allows drop-in replacement between grades when package type and temperature range align with system requirements.
