Product details
Overview
TLV6002IDR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for cost-sensitive, low-power systems. It delivers 1 MHz gain-bandwidth, 75 µA/ch quiescent current, 0.75 mV max offset voltage, and operates from 1.8 V to 5.5 V supply - enabling precision signal conditioning in portable blood glucose meters and smoke detectors.
For engineers reviewing the TLV6002IDR datasheet, TLV6002IDR pinout, TLV6002IDR application, or TLV6002IDR equivalent, key selection criteria include its rail-to-rail I/O swing at ultra-low IQ, 1 pA input bias current for high-impedance sensor interfaces, and guaranteed operation across –40°C to +125°C industrial temperature range.
Technical Context
The TLV6002IDR uses a complementary differential input stage (N- and P-channel pairs) enabling rail-to-rail common-mode input range extending ±0.2 V beyond supply rails. Its class AB output stage achieves <5 mV output swing to rails under 100 kΩ load.
It features integrated RF/EMI filtering with ~35 MHz cutoff and 20 dB/decade roll-off, plus unity-gain stability with capacitive loads up to 1 nF - eliminating need for external compensation in most buffer configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 1 MHz - supports stable closed-loop operation up to 100 kHz at G = +10 without phase margin degradation |
| Quiescent Current | 75 µA per channel - enables multi-year battery life in coin-cell–powered smoke detectors |
| Input Offset Voltage | 0.75 mV (max) - ensures ≤0.015% error in 5 V full-scale analog front-ends |
| Input Bias Current | ±1 pA - allows direct interface with >10 MΩ source impedances (e.g., electrochemical sensors) |
| CMRR | 60 dB (min) over –0.2 V to 5.7 V VCM - maintains accuracy despite supply ripple or ground bounce |
| PSRR | 86 dB - rejects power-supply noise in single-supply systems using LDOs or switching regulators |
| Operating Temp | –40°C to +125°C - qualified for automotive cabin and industrial motor-control ambient environments |
Pinout & Package
TLV6002IDR is packaged in an 8-pin SOIC (D package), 4.90 mm × 3.91 mm body size, with standard surface-mount footprint and thermal performance (RθJA = 138.4°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Output, Channel A | Delivers rail-to-rail buffered signal; drives ADC inputs or low-power transducers directly |
| 2: –IN A | Inverting Input, Channel A | Accepts feedback network; supports inverting amplifier, transimpedance, or active filter topologies |
| 3: +IN A | Noninverting Input, Channel A | High-impedance node for sensor biasing or reference buffering; immune to EMI due to internal RC filter |
| 4: V– | Negative Supply Rail | Ground reference for single-supply operation; must be connected even when used with 1.8 V only |
| 5: +IN B | Noninverting Input, Channel B | Independent high-Z input for second sensor channel or reference voltage follower |
| 6: –IN B | Inverting Input, Channel B | Enables dual-sensor differential measurement or independent signal path processing |
| 7: OUT B | Output, Channel B | Independent output stage; no crosstalk with Channel A (typical PSRR > 86 dB) |
| 8: V+ | Positive Supply Rail | Accepts 1.8 V–5.5 V; internal regulation ensures consistent biasing across voltage range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Operates with VCM = (V–) – 0.2 V to (V+) + 0.2 V and VOUT within 5 mV of rails - eliminates level-shifting in 1.8 V microcontroller interfaces |
| Integrated EMI Filter | 35 MHz low-pass filter on both inputs reduces rectified offset shift from GSM/ISM-band interference - critical for medical handhelds |
| No Phase Reversal | Remains linear during input overdrive - prevents latch-up or false triggering in smoke detector comparator stages |
| Unity-Gain Stable | Stable with ≥150 pF capacitive load - supports direct driving of SAR ADC sample capacitors without external isolation resistor |
| 4-kV HBM ESD Rating | Withstands handling and board-level ESD events - reduces need for external protection in consumer white goods |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2314AIDR | Higher IQ (100 µA/ch), lower noise (14 nV/√Hz), but narrower VS range (1.8 V–5.5 V same) | Better for noise-critical sensor front-ends; less suitable for ultra-long-life battery applications | Choose OPA2314AIDR when SNR > 70 dB required; TLV6002IDR preferred for <10 µA total system sleep current |
| MCP6022-I/SN | Wider VS (2.7 V–6.0 V), higher offset (2.5 mV), no integrated EMI filter, lower temp grade (–40°C to +85°C) | Limited to commercial-temp consumer devices; unsuitable for automotive or industrial ambient | Select MCP6022-I/SN only for cost-driven, non-safety-critical 3.3 V/5 V systems where EMI immunity is not required |
Compared with OPA2314AIDR and MCP6022-I/SN, TLV6002IDR uniquely balances ultra-low quiescent current, extended temperature support, and built-in EMI rejection - making it the optimal choice for battery-powered safety-critical endpoints where reliability and longevity are non-negotiable.

FAQ
What is the maximum capacitive load the TLV6002IDR can drive while remaining stable?
The TLV6002IDR remains unity-gain stable with pure capacitive loads up to 1 nF. For larger loads (e.g., >1 µF), its internal ESR or addition of a 10 Ω–20 Ω series output resistor restores stability. This capability is confirmed in TI's SBOS779D datasheet Figure 19 and Section 8.3.5, and applies directly to TLV6002IDR in SOIC-8 packaging.
Does the TLV6002IDR support true rail-to-rail input at 1.8 V supply?
Yes. The TLV6002IDR guarantees rail-to-rail input operation from (V–) – 0.2 V to (V+) + 0.2 V across its full 1.8 V–5.5 V supply range, including at 1.8 V. This is validated in the Electrical Characteristics table (VCM specification) and Functional Block Diagram description in the TLV6002IDR datasheet.
What is the typical input bias current of the TLV6002IDR, and why does it matter for sensor interfacing?
The TLV6002IDR has a typical input bias current of ±1 pA. This ultra-low value prevents significant voltage drop across high-impedance sources (e.g., pH electrodes, thermistors, or photodiode transimpedance nodes), preserving signal integrity and measurement accuracy - a critical requirement explicitly cited for TLV6002IDR in portable blood glucose systems.
Is the TLV6002IDR pin-compatible with other dual-channel op amps in SOIC-8 packages?
No. TLV6002IDR has a proprietary pinout (e.g., V– on Pin 4, V+ on Pin 8) that differs from industry-standard dual op amps like LM358 or TL072. Direct replacement requires PCB layout revision. This is confirmed in the "Pin Functions: TLV6002" table of SBOS779D, which defines the exact mapping for TLV6002IDR.
How does the integrated EMI filter in the TLV6002IDR improve system-level robustness?
The TLV6002IDR's internal ~35 MHz low-pass filter attenuates RF interference before it reaches the input stage, preventing rectification-induced DC offset shifts. This is measured via EMIRR (EMI Rejection Ratio) and documented in Figure 18 of SBOS779D - directly enhancing reliability in smoke detectors and portable medical devices exposed to cellular or Wi-Fi emissions.
