Product details
Overview
TLC2202CDR from Texas Instruments is a dual, precision, low-noise rail-to-rail output operational amplifier using Advanced LinCMOS™ process. It delivers 500 µV max input offset voltage, 30 nV/√Hz max noise at 10 Hz, and operates from ±2.3 V to ±8 V supplies across 0°C to 70°C. It serves in high-impedance sensor signal conditioning, medical instrumentation front-ends, and single-supply data acquisition systems.
For engineers reviewing the TLC2202CDR datasheet, TLC2202CDR pinout, TLC2202CDR application, or TLC2202CDR equivalent, key selection criteria include its rail-to-rail output swing, sub-1 pA input bias current, common-mode input range extending to the negative rail, and guaranteed noise performance over temperature - critical for low-level analog measurement integrity.
Technical Context
The TLC2202CDR 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 processes. Its input stage includes JFET-like high impedance (1 pA typ input bias) while retaining bipolar-grade DC precision.
Each amplifier features fully differential input topology with common-mode range including the negative supply rail, rail-to-rail output stage capable of ±4.7 V swing into 10 kΩ with ±5 V supplies, and internal ESD protection rated to 2000 V per MIL-PRF-38535 Method 3015.2.
Key Specifications

|---|---|
| Input Offset Voltage | 500 µV max at 25°C - ensures minimal DC error in precision gain stages and sensor bridges. |
| Input Bias Current | 1 pA typ at 25°C - enables use with ultra-high-impedance sources (e.g., piezoelectric sensors, pH electrodes) without significant loading error. |
| Input Noise Voltage | 30 nV/√Hz max at 10 Hz - supports low-frequency, high-resolution measurements in EEG, strain gauge, and thermocouple amplifiers. |
| Rail-to-Rail Output | ±4.7 V swing into 10 kΩ with ±5 V supplies - maximizes dynamic range in single-supply or split-supply data acquisition channels. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows direct sensing of signals referenced to ground in single-supply configurations. |
| Supply Voltage Range | ±2.3 V to ±8 V - supports operation from low-voltage battery-powered systems up to industrial ±5 V rails. |
| Gain-Bandwidth Product | 1.9 MHz - sufficient for anti-aliasing filters, active instrumentation amplifiers, and closed-loop gains ≤100 with stable phase margin. |
Pinout & Package
Package: SOIC-8 (D package), 8-pin small-outline integrated circuit with standard 1.27 mm pitch; RoHS-compliant, tape-and-reel (R suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 (1OUT) | Low-impedance rail-to-rail output node; drives ADC inputs, filter stages, or downstream buffers directly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277UA | Lower offset (10 µV max), higher cost, bipolar input (2 nA bias), no rail-to-rail output. | Better DC precision but incompatible with rail-to-rail output requirements or ultra-high-Z sources. | Select when ultra-low offset dominates over input impedance and output swing constraints. |
| MCP6022-I/SN | Higher noise (25 nV/√Hz typ at 1 kHz), wider supply (2.7–6 V), CMOS input (1 pA), rail-to-rail I/O. | Compatible rail-to-rail behavior but unqualified below 0°C and lacks guaranteed 10 Hz noise spec. | Select for cost-sensitive commercial designs operating strictly within 0°C–70°C with relaxed low-frequency noise needs. |
Compared with OPA2277UA and MCP6022-I/SN, the TLC2202CDR uniquely balances sub-1 pA bias, guaranteed 30 nV/√Hz at 10 Hz, rail-to-rail output, and −40°C to 125°C qualified variants - making it optimal for ruggedized, low-frequency precision signal chains where both input impedance and noise are simultaneously critical.

FAQ
What is the maximum input common-mode voltage range for the TLC2202CDR?
The TLC2202CDR supports a common-mode input voltage range from VDD− to (VDD+ − 2.3 V) across its full operating temperature range. With ±5 V supplies, this spans −5 V to +2.7 V - explicitly including the negative rail, enabling true single-supply operation with ground-referenced inputs. This specification is guaranteed per the recommended operating conditions table in the SLOS175B datasheet.
Does the TLC2202CDR support rail-to-rail output swing under load?
Yes, the TLC2202CDR delivers rail-to-rail output swing: ±4.7 V into a 10 kΩ load with ±5 V supplies, and maintains >94% of full-scale swing even at 1 mA load. This is verified in the electrical characteristics tables (VOM+ and VOM− parameters) and applies across 0°C to 70°C. The output stage is designed to drive moderate loads without clipping near supply rails.
What is the guaranteed input voltage noise specification for the TLC2202CDR at 10 Hz?
The TLC2202CDR is guaranteed to deliver ≤30 nV/√Hz equivalent input noise voltage at 10 Hz, as stated in the "TLC2202 AVAILABLE OPTIONS" table and confirmed in the "TLC2202C electrical characteristics" section of the SLOS175B datasheet. This value is tested and specified for the C-suffix (0°C to 70°C) grade, which matches the TLC2202CDR's temperature qualification.
Can the TLC2202CDR operate from a single 5 V supply?
Yes, the TLC2202CDR is fully specified for single-supply operation. When VDD− is connected to ground and VDD+ to 5 V, the device operates with common-mode input range from 0 V to 2.7 V and rail-to-rail output swing from ~0 V to ~4.7 V. This configuration is explicitly supported in the datasheet's "Fully Specified For Both Single-Supply and Split-Supply Operation" statement and validated in the VDD = 5 V characterization tables.
What is the typical supply current consumption of the TLC2202CDR?
The TLC2202CDR draws 1.8–2.7 mA total supply current (IDD) per dual amplifier at 25°C with ±5 V supplies and no load, as specified in the "TLC2202C electrical characteristics" table. This represents ~1.35 mA per amplifier - a balanced trade-off between low-noise performance and power efficiency for precision analog signal chains.
