Product details
Overview
TLV6002IDGKR 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 TLV6002IDGKR datasheet, TLV6002IDGKR pinout, TLV6002IDGKR application, or TLV6002IDGKR equivalent, this page provides verified electrical specs, VSSOP-8 package details, real-world use cases, and two validated alternative op-amps with documented functional and application-level differences.
Technical Context
The TLV6002IDGKR uses a complementary differential input stage (N- and P-channel pairs) enabling rail-to-rail input operation with ±0.2 V beyond supply rails. Its class AB output stage achieves 5 mV rail-to-rail swing into 100 kΩ loads at 1.8–5.5 V supplies.
It features integrated RF/EMI filtering (35 MHz –3 dB cutoff), unity-gain stability up to 1 nF capacitive load, and no phase reversal under overdrive - all while maintaining 60–76 dB CMRR and 86 dB PSRR across –40°C to +125°C.
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 compensation. |
| Quiescent Current | 75 µA per channel - enables multi-year battery life in smoke detectors and portable medical devices. |
| Input Offset Voltage | 0.75 mV (max) - ensures ≤0.015% error in 5 V full-scale ADC front-ends. |
| Supply Range | 1.8 V to 5.5 V - compatible with single-cell Li-ion, 2×AA, and 3.3 V/5 V system rails. |
| CMRR / PSRR | 60–76 dB CMRR, 86 dB PSRR - rejects common-mode noise and supply ripple in noisy industrial environments. |
| Input Bias Current | ±1.0 pA (typ) - preserves accuracy with >10 MΩ sensor source impedances (e.g., electrochemical glucose sensors). |
| Output Swing | Within 5 mV of rails (RL = 100 kΩ) - maximizes dynamic range for 12-bit+ SAR ADCs. |
Pinout & Package
VSSOP-8 package: 3.00 mm × 3.00 mm body, 0.65 mm lead pitch, exposed thermal pad (DGK suffix). Pin 1 marked by beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives ADC input or transducer interface with rail-to-rail swing. |
| 2 | –IN A | Inverting input, channel A - used in inverting configurations or feedback networks. |
| 3 | +IN A | Noninverting input, channel A - connects to high-impedance sensors (e.g., pH electrode). |
| 4 | V– | Negative supply rail - tied to ground in single-supply systems (0 V reference). |
| 5 | +IN B | Noninverting input, channel B - independent input for dual-sensor monitoring (e.g., temperature + humidity). |
| 6 | –IN B | Inverting input, channel B - supports differential sensing or active filtering on second channel. |
| 7 | OUT B | Amplifier B output - enables simultaneous signal conditioning without external multiplexing. |
| 8 | V+ | Positive supply rail - accepts 1.8–5.5 V; internal ESD diodes clamp inputs to these rails. |
Key Features

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 |
|---|---|---|---|
| LMV358IDR | Higher IQ (150 µA/ch), lower GBW (1 MHz same), no EMI filter, 1.5 mV offset. | Not suitable for EMI-prone medical devices; acceptable in industrial controls where noise immunity is secondary. | Choose LMV358IDR only if cost is primary constraint and EMI rejection is not required. |
| OPA316IDBVR | Lower noise (11 nV/√Hz), higher IQ (100 µA/ch), same GBW, no integrated EMI filter. | Better for high-fidelity audio preamps; lacks EMI hardening needed in portable consumer safety devices. | Select OPA316IDBVR when ultra-low noise dominates design priority and EMI environment is controlled. |
Compared with LMV358IDR and OPA316IDBVR, TLV6002IDGKR uniquely combines EMI filtering, 1 pA bias current, and 75 µA quiescent current - making it the only option qualified for battery-powered safety-critical analog front-ends where both precision and robustness are mandatory.

FAQ
What is the maximum capacitive load the TLV6002IDGKR can drive without oscillation?
The TLV6002IDGKR remains unity-gain stable with pure capacitive loads up to 1 nF. This capability eliminates external compensation in ADC buffer applications. For loads exceeding 1 nF, adding a 10–20 Ω series resistor at the output reduces ringing while maintaining stability - though it introduces minor gain error due to voltage division with parallel load resistance. The TLV6002IDGKR's internal architecture avoids phase reversal under overdrive, further enhancing reliability in transient-heavy environments.
Does the TLV6002IDGKR support true rail-to-rail input at 1.8 V supply?
Yes, the TLV6002IDGKR supports 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 the input common-mode range extends from –0.2 V to +2.0 V. This is achieved via a complementary N/P-channel input stage that seamlessly transitions between pairs - enabling accurate sensing of signals near ground or near the positive rail in single-supply portable systems using the TLV6002IDGKR.
How does the integrated EMI filter in the TLV6002IDGKR improve system-level robustness?
The TLV6002IDGKR incorporates an internal low-pass filter with ~35 MHz –3 dB cutoff on both inputs, providing common-mode and differential-mode EMI rejection. This reduces rectification-induced offset shifts caused by RF interference (e.g., GSM, WiFi), which is critical in portable medical devices like blood glucose meters. Unlike external RC filters, this integrated solution avoids added noise, board space, and component count - directly improving measurement integrity in EMI-prone environments without design overhead. The TLV6002IDGKR's EMIRR performance is characterized and published in TI's SBOA128 application report.
Can the TLV6002IDGKR operate reliably at –40°C for industrial applications?
Yes, the TLV6002IDGKR is fully specified and production-tested over –40°C to +125°C. Electrical parameters including input offset voltage (0.75 mV max), CMRR (60 dB min), and quiescent current (75 µA typ) are guaranteed across this range. Its robust ESD protection (4-kV HBM), no-phase-reversal behavior under overdrive, and rail-to-rail performance at temperature extremes make it suitable for industrial motor control, outdoor sensor nodes, and automotive cabin modules - all validated in the TLV6002IDGKR's official characterization data.
What is the typical input voltage noise density of the TLV6002IDGKR at 1 kHz?
The TLV6002IDGKR has a typical input voltage noise density of 28 nV/√Hz at 1 kHz, as confirmed in the SBOS779D datasheet Section 7.7. This value is measured under standard conditions (TA = 25°C, VS = 5 V, RL = 10 kΩ). Combined with its 1 pA input bias current and rail-to-rail input, this noise performance supports high-accuracy signal acquisition from high-impedance sources such as electrochemical sensors and piezoresistive elements - a key differentiator of the TLV6002IDGKR in portable instrumentation.
