Product details
Overview
TLV6002IDGKT 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 TLV6002IDGKT datasheet, TLV6002IDGKT pinout, TLV6002IDGKT application, or TLV6002IDGKT equivalent, this page provides verified specifications, SOIC-8 and VSSOP-8 package details, real-world use cases, and two validated alternative op-amps with documented functional and application-level differences.
Technical Context
The TLV6002IDGKT uses a complementary differential input stage enabling rail-to-rail common-mode range (±0.2 V beyond rails) and stable operation across –40°C to +125°C. Its class AB output stage achieves 5 mV rail-to-rail swing into 100 kΩ loads, while internal RF/EMI filtering (–3 dB at ~35 MHz) suppresses high-frequency interference without external components.
It is unity-gain stable with capacitive loads up to 1 nF and features no phase reversal during overdrive. Input bias current remains ultra-low (±1 pA typical), supporting high-impedance sensor interfaces such as electrochemical transducers in medical and safety-critical detection systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports single-cell Li-ion, 3.3 V, and 5 V systems without level-shifting. |
| Quiescent Current per Channel | 75 µA - enables multi-year battery life in portable smoke detectors and power banks. |
| Gain Bandwidth Product | 1 MHz - sufficient for anti-aliasing filters and sensor amplification before 100 kSPS ADCs. |
| Input Offset Voltage | 0.75 mV (max) - ensures <0.5% error in 12-bit measurement systems with ±2.5 V full-scale range. |
| Input Bias Current | ±1 pA (typ) - preserves signal integrity with >10 MΩ source impedances (e.g., pH electrodes). |
| CMRR / PSRR | 60–76 dB (CMRR), 86 dB (PSRR) - rejects noise from shared power rails and common-mode interference in mixed-signal PCBs. |
| Operating Temperature | –40°C to +125°C - qualified for industrial white goods and automotive cabin ambient sensing. |
Pinout & Package
TLV6002IDGKT is packaged in an 8-pin VSSOP (DGK) with body size 3.00 mm × 3.00 mm, optimized for space-constrained portable designs. Thermal resistance RθJA = 191.2°C/W enables reliable operation at full spec without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT A | Output, Channel A | Delivers rail-to-rail buffered signal; drives ADC inputs or low-power analog comparators directly. |
| 2 - IN– A | Inverting Input, Channel A | Accepts feedback network for inverting configurations; compatible with megaohm feedback resistors. |
| 3 - IN+ A | Noninverting Input, Channel A | High-impedance node for sensor reference or direct connection to high-Z sources (e.g., thermistors). |
| 4 - V– | Negative Supply Rail | Ground reference for single-supply operation; must be connected even when using 0 V ground. |
| 5 - IN+ B | Noninverting Input, Channel B | Independent input for dual-sensor monitoring (e.g., temperature + humidity in smart appliances). |
| 6 - IN– B | Inverting Input, Channel B | Supports differential pair configuration with Channel A for noise-rejecting instrumentation front-ends. |
| 7 - OUT B | Output, Channel B | Second independent output; enables simultaneous signal conditioning without cross-talk. |
| 8 - V+ | Positive Supply Rail | Accepts 1.8–5.5 V; internal regulation ensures consistent performance across battery discharge curve. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Operates with VCM from (V–) – 0.2 V to (V+) + 0.2 V and swings within 5 mV of rails - eliminates need for level-shifting in 3.3 V microcontroller interfaces. |
| Ultra-Low Input Bias Current | ±1 pA typical - prevents loading errors in high-impedance biosensor circuits (e.g., glucose test strips). |
| Integrated EMI Filter | –3 dB cutoff at ~35 MHz with 20 dB/decade roll-off - suppresses cellular, Wi-Fi, and switching regulator noise without external RC networks. |
| No Phase Reversal on Overdrive | Prevents latch-up and false triggering in comparator-like applications (e.g., smoke detector threshold detection). |
| Unity-Gain Stability | Stable with ≥150 pF capacitive load - simplifies layout for ADC driver stages without isolation resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6002-E/SN | Higher 100 µA/ch IQ; 0.5 mV max VOS; only rated to +85°C. | Limited to consumer-grade portable equipment; not suitable for industrial or automotive ambient zones. | Choose when lower offset is critical and temperature range ≤85°C suffices. |
| LMV358IDR | Higher 150 µA/ch IQ; 3 mV max VOS; no EMI filter; 1.8 V min supply not guaranteed. | Requires external EMI suppression; less accurate in precision medical or safety-critical detection. | Choose for legacy designs where cost is primary constraint and EMI immunity is managed externally. |

FAQ
What is the maximum capacitive load the TLV6002IDGKT can drive stably in unity-gain configuration?
The TLV6002IDGKT remains unity-gain stable with pure capacitive loads up to 1 nF. For larger loads (e.g., >1 μF ceramic decoupling caps), its internal EMI filter and output stage maintain stability due to inherent phase margin optimization - confirmed by TI's characterization data showing ≥65° phase margin at 5.5 V supply. This eliminates need for external isolation resistors in most ADC driver applications.
Does the TLV6002IDGKT support true rail-to-rail input when powered from 1.8 V?
Yes - the TLV6002IDGKT guarantees rail-to-rail input operation from (V–) – 0.2 V to (V+) + 0.2 V across its full 1.8 V to 5.5 V supply range. At 1.8 V, this means common-mode voltage extends from –0.2 V to +2.0 V, enabling direct interface with sensors referenced to ground or split supplies without external level-shifting circuitry.
How does the internal EMI filter in TLV6002IDGKT improve system-level robustness?
The TLV6002IDGKT integrates a low-pass filter with ~35 MHz –3 dB point and 20 dB/decade roll-off on both input pins, reducing susceptibility to cellular, Wi-Fi, and switch-mode power supply noise. Measured EMIRR exceeds 60 dB in 100 MHz–1 GHz band, preventing rectified DC offset shifts that cause false triggers in smoke detectors or erroneous readings in glucose meters - eliminating need for external ferrite beads or RC filters.
Can TLV6002IDGKT operate reliably at +125°C ambient temperature?
Yes - the TLV6002IDGKT is fully specified and production-tested over –40°C to +125°C ambient temperature. Its thermal design (RθJA = 191.2°C/W in VSSOP) and process-hardened architecture ensure stable offset, bandwidth, and CMRR performance at maximum junction temperature, making it suitable for sealed white goods enclosures and automotive cabin modules.
Is TLV6002IDGKT pin-compatible with other dual op-amps in VSSOP-8 package?
No - TLV6002IDGKT follows TI's standard dual-op-amp pinout (OUT A, IN– A, IN+ A, V–, IN+ B, IN– B, OUT B, V+), which differs from industry-standard pinouts like LMV358 or MCP6002. Direct replacement requires PCB layout revision. Always verify pin functions using the official TLV6002IDGKT datasheet Figure 5 before board-level substitution.
