Product details
Overview
TLC2202IP from Texas Instruments is a dual, precision, low-noise operational amplifier using Advanced LinCMOS™ process. It delivers 500 µV max input offset voltage, 30 nV/√Hz max noise at 10 Hz, rail-to-rail output swing, and operates from ±2.3 V to ±8 V supplies. It serves in high-impedance sensor signal conditioning and single-supply data acquisition front-ends.
For engineers reviewing the TLC2202IP datasheet, TLC2202IP pinout, TLC2202IP application, or TLC2202IP equivalent, key selection criteria include input offset stability (0.5 µV/°C typ), ultra-low bias current (1 pA typ), common-mode range extending to the negative rail, and verified performance across −40°C to +85°C industrial temperature range.
Technical Context
The TLC2202IP integrates two independent precision op-amps on a single die using silicon-gate Advanced LinCMOS™ technology, enabling superior input offset voltage stability over time and temperature versus metal-gate alternatives. Its input stage supports common-mode voltages down to the negative supply rail, and outputs swing within 200 mV of both rails under 10-kΩ load.
Each amplifier features JFET-like input impedance (>1012 Ω) combined with bipolar-grade DC precision. The device is fully specified for both split-supply (±2.3 V to ±8 V) and single-supply operation, with internal ESD protection rated to 2000 V per MIL-PRF-38535 Method 3015.2.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277PA | Lower offset (10 µV max), higher cost, SO-8 package only - no DIP option | Preferred where ultra-low offset dominates over noise and package form factor | Select when VIO < 50 µV is mandatory and through-hole mounting is not required |
| LMC6082IMX | Higher input bias (25 fA typ), wider supply (2.7–15 V), same DIP-8 footprint - pin-compatible | Better suited for battery-powered, single-supply systems needing extended VDD range | Choose when operating from 3.3 V or 5 V only, and sub-picoampere bias is essential |
Compared with OPA2277PA and LMC6082IMX, the TLC2202IP uniquely balances low 1/f noise, industrial temperature rating, through-hole DIP packaging, and cost-effective precision-making it optimal for legacy industrial hardware upgrades and sensor interface boards requiring mechanical robustness and long-term calibration stability.

FAQ
What is the maximum supply voltage rating for the TLC2202IP?
The TLC2202IP has an absolute maximum supply voltage rating of ±8 V across VDD+ and VDD− terminals. Operation beyond this limit risks permanent damage. Recommended operating range is ±2.3 V to ±8 V, with full electrical specifications guaranteed across that span for the −40°C to +85°C temperature range. Always observe derating curves in the datasheet for elevated ambient temperatures.
Does the TLC2202IP support true rail-to-rail input?
No, the TLC2202IP does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD−) but only up to VDD+ − 2.3 V. However, its output is rail-to-rail - swinging within 200 mV of both supply rails under 10-kΩ load. This makes it ideal for output buffering and single-supply applications where input signals remain above the negative rail.
Can the TLC2202IP be used in a single-supply configuration?
Yes, the TLC2202IP is fully specified for single-supply operation. When powered from a 5-V supply (VDD+ = 5 V, VDD− = GND), it operates with common-mode input down to 0 V and output swing from ~20 mV to ~4.8 V. Designers must bias inputs appropriately - e.g., using a mid-supply reference - and ensure input signals stay within the validated common-mode range (0 V to 2.7 V).
What is the typical input bias current of the TLC2202IP at 25°C?
The typical input bias current of the TLC2202IP is 1 pA at 25°C, with a maximum of 100 pA across the full −40°C to +85°C operating range. This ultra-low value results from the Advanced LinCMOS™ process and enables high-impedance sensor interfacing - such as photodiodes, pH electrodes, or piezoresistive elements - without significant signal attenuation or offset shift.
Is the TLC2202IP pin-compatible with other devices in the TLC220x family?
Yes, all TLC220x dual op-amps in the 8-pin DIP (P), SOIC (D), and PS packages share identical pinouts - including TLC2202IP, TLC2202CP, TLC2202ACD, and TLC2202BIP. Pin functions (1OUT, 1IN−, 1IN+, VDD−/GND, 2IN+, 2IN−, 2OUT, VDD+) are consistent across variants. Differences lie solely in grade (A/B/C), temperature range (I-suffix = −40°C to +85°C), and electrical specifications - not physical layout.
