Product details
Overview
TLC2810ZP from Texas Instruments is a LinCMOS™ precision dual operational amplifier optimized for single-supply operation across –40°C to 150°C, featuring 10 mV max input offset voltage at 25°C, 25 nV/√Hz typical input noise at 1 kHz, and rail-to-rail output swing down to the negative rail. It delivers high input impedance (10¹² Ω typ), low bias current (7 pA typ at 25°C), and operates from 4 V to 16 V supply - enabling use in high-temperature transducer interfacing and industrial analog signal conditioning.
For engineers reviewing the TLC2810ZP datasheet, TLC2810ZP pinout, TLC2810ZP application, or TLC2810ZP equivalent, key selection criteria include its extended temperature rating (–40°C to 150°C), input offset voltage drift (0.1 µV/month), common-mode input range extending to the negative rail, and ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2.
Technical Context
The TLC2810ZP implements silicon-gate LinCMOS™ technology to achieve superior offset stability over metal-gate processes, with input offset voltage drift as low as 3.5 µV/°C over –25°C to 150°C. Its architecture supports single-supply operation via rail-referenced input stage design and output stage capable of sinking to GND.
It integrates internal ESD-protection circuitry that prevents functional failure up to 2000 V HBM, while maintaining latch-up immunity per design-in specifications. The device's differential input structure tolerates ±VDD differential voltage and accepts input signals from –0.3 V to VDD, with surge current tolerance of –100 mA on inputs/outputs without latch-up at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 16 V - enables direct interface with TTL/CMOS logic supplies and battery-powered systems down to 4 V. |
| Operating Temperature | –40°C to 150°C - qualified for under-hood automotive, downhole oil/gas, and industrial furnace monitoring. |
| Input Offset Voltage | 10 mV max at 25°C - ensures ≤1% gain error in unity-gain buffer configurations with 1 V input. |
| Input Noise Density | 25 nV/√Hz typ at 1 kHz - supports low-noise amplification of microvolt-level sensor outputs (e.g., thermocouples). |
| Common-Mode Input Range | Extends to negative rail (GND) - allows direct sensing of ground-referenced signals without level-shifting circuitry. |
| Output Voltage Swing | Includes negative rail - delivers full dynamic range when driving ADCs or comparators referenced to GND. |
| Input Impedance | 10¹² Ω typ - minimizes loading on high-impedance sources such as piezoelectric sensors or pH electrodes. |
Pinout & Package
Package: Plastic DIP (P), 8-pin through-hole, 0.300-inch wide body, JEDEC MS-001AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Inverting amplifier output - drives loads up to ±30 mA; rail-to-rail swing enables full utilization of 0–5 V ADC input ranges. |
| 2 | IN1– | Inverting input - differential pair gate node; high impedance requires guarded layout to avoid leakage-induced offset. |
| 3 | IN1+ | Non-inverting input - referenced to GND in single-supply mode; accepts signals from –0.3 V to VDD without damage. |
| 4 | GND | Analog ground reference - must be star-connected to minimize noise coupling into high-impedance inputs. |
| 5 | VDD | Positive supply rail - total supply current ≤4.4 mA (full temp range); decoupling capacitor required within 1 cm. |
| 6 | OUT2 | Second amplifier output - independent channel enables dual-sensor conditioning or active filter stages. |
| 7 | IN2– | Second inverting input - electrically isolated from IN1–; supports differential input configurations with matched traces. |
| 8 | IN2+ | Second non-inverting input - identical electrical characteristics to IN1+; enables parallel signal paths with matched gain. |
Key Features
| Feature | Design Value |
|---|---|
| Latch-up immunity | Designed-in immunity per JEDEC JESD78 - eliminates risk of destructive latch-up during power sequencing or transient events. |
| ESD protection | 2000 V HBM per MIL-STD-883C Method 3015.2 - reduces handling sensitivity and field-failure risk in uncontrolled environments. |
| Trimmed offset voltage | 10 mV max at 25°C - reduces need for external nulling circuits in precision instrumentation front-ends. |
| Low long-term drift | 0.1 µV/month typical - ensures stable calibration over multi-year deployments in embedded monitoring systems. |
| High-temperature operation | 150°C maximum operating temperature - supports placement near heat sources (e.g., engine blocks, motor controllers). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2CP | Lower supply current (1.6 mA typ), but higher input offset (19 mV max) and narrower temp range (–40°C to 85°C). | Suitable only for commercial-temp consumer electronics; not rated for >85°C operation. | Select when ultra-low power dominates over precision and temperature range. |
| OPA2333PA | Zero-drift architecture, 2 µV max offset, but limited to 125°C max operating temperature and higher cost. | Preferred for sub-µV offset requirements in medical or test equipment where 150°C is unnecessary. | Select when nanovolt-level offset stability outweighs extended temperature capability and BOM cost. |
Compared with TLC27L2CP, the TLC2810ZP provides 90°C wider temperature coverage and 1.9× lower input offset; compared with OPA2333PA, it trades 2 µV offset for +25°C operating margin and 40% lower unit cost - making TLC2810ZP optimal for high-temp industrial signal conditioning where <10 mV offset is acceptable.

FAQ
What is the maximum operating temperature of the TLC2810ZP?
The TLC2810ZP is characterized for continuous operation from –40°C to 150°C ambient temperature. This rating is verified per TI's SLOS120A datasheet and applies to both DC and AC performance parameters including input offset voltage, slew rate, and CMRR. Operation beyond 150°C risks parametric degradation and is not guaranteed.
Does the TLC2810ZP support true rail-to-rail input and output?
The TLC2810ZP features rail-to-rail output swing (including the negative rail) and common-mode input voltage range extending to the negative rail (GND), but does not support full rail-to-rail input - the positive input limit is VDD – 1.2 V at 25°C. This design enables robust single-supply operation while maintaining LinCMOS™ process advantages.
Can the TLC2810ZP be used with a 3.3 V supply?
No - the TLC2810ZP has a minimum specified supply voltage of 4 V per its recommended operating conditions. At 3.3 V, key parameters including output drive strength, CMRR, and input bias current fall outside datasheet guarantees, and functionality is not assured. Use TI's TLV2462 or OPA2340 for 2.7–5.5 V operation.
What is the input offset voltage drift specification for the TLC2810ZP?
The TLC2810ZP exhibits an average temperature coefficient of input offset voltage (αVIO) of 3.5 µV/°C over –25°C to 150°C, with long-term drift typically 0.1 µV/month including the first 30 days. These values are measured per SLOS120A and reflect LinCMOS™ process stability advantages over metal-gate alternatives.
Is the TLC2810ZP pin-compatible with other TI dual op-amps like the TLC272?
No - the TLC2810ZP uses an industry-standard 8-pin DIP pinout (1:OUT1, 2:IN1–, 3:IN1+, 4:GND, 5:VDD, 6:OUT2, 7:IN2–, 8:IN2+), but its internal architecture, biasing, and ESD structures differ significantly from TLC272. Direct substitution may cause instability, incorrect common-mode range, or thermal runaway due to differing quiescent current and input stage design.
