Product details
Overview
TLV341IDCKR from Texas Instruments is a single-channel, low-voltage, rail-to-rail output CMOS operational amplifier with active-low shutdown control, designed for ultra-low-power (70 μA/channel typical) and precision (1.25 mV max offset at 25°C) operation across 1.5 V to 5.5 V supply rails. It features 2.3 MHz gain bandwidth, 0.9 V/μs slew rate, and 1 pA input bias current - enabling high-accuracy signal conditioning in space-constrained battery-powered systems such as portable audio preamplifiers and supply current monitors.
For engineers reviewing the TLV341IDCKR datasheet, TLV341IDCKR pinout, TLV341IDCKR application, or TLV341IDCKR equivalent, key selection considerations include its SC70-6 package footprint, shutdown current of 10 pA (typ), rail-to-rail output swing within 7 mV of rails (at 10 kΩ load), extended industrial temperature range (–40°C to 125°C), and compatibility with 1.5 V single-supply operation - critical for modern ultra-low-voltage sensor interfaces and energy-harvesting front ends.
Technical Context
The TLV341IDCKR employs a PMOS input stage enabling rail-to-rail common-mode input range (–0.2 V to V+ – 0.5 V) and ultra-low input bias current (1 pA typ), while its CMOS output stage delivers true rail-to-rail output swing (within 7 mV of V+ and GND at 10 kΩ). Its shutdown mode reduces supply current to 10 pA per channel and places the output in high-impedance state.
Functional operation supports single-supply configurations from 1.5 V to 5.5 V, with guaranteed performance across –40°C to 125°C. The active-low SHDN pin enables fast turnon (5 μs typ) and full system-level power gating - essential for duty-cycled sensing nodes and portable instrumentation requiring dynamic power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5 V to 5.5 V - supports direct integration into Li-ion, coin-cell, and energy-harvesting power domains without level-shifting. |
| Input Offset Voltage (max) | 1.25 mV at 25°C (A grade) - ensures ≤0.1% gain error in 12-bit precision signal chains without trimming. |
| Supply Current (typ) | 70 μA per channel - enables >1-year battery life in 10-μA average-current IoT sensor nodes. |
| Gain Bandwidth Product | 2.3 MHz - sufficient for anti-aliasing filters up to ~200 kHz and audio-band amplification (20 Hz–20 kHz). |
| Rail-to-Rail Output Swing | Within 7 mV of V+ and GND (RL = 10 kΩ) - maximizes dynamic range in 1.8 V and 3.3 V ADC interfaces. |
| Shutdown Current (typ) | 10 pA - allows microcontroller-controlled deep-sleep modes with negligible leakage impact on system standby current. |
| Input Bias Current (typ) | 1 pA - preserves signal integrity in high-impedance pH, photodiode, and piezoelectric sensor front ends. |
Pinout & Package
TLV341IDCKR is packaged in a 6-pin SC70 (DCK) package measuring 2.00 mm × 1.25 mm, optimized for ultra-compact PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Noninverting input | Accepts analog signals down to –0.2 V; compatible with ground-referenced sensors and single-supply transducer interfaces. |
| 2 (GND) | Ground reference | Primary return path for supply and signal currents; must be low-impedance and separated from digital ground in mixed-signal designs. |
| 3 (IN−) | Inverting input | Supports precision inverting amplifier, transimpedance, and differential configurations with matched input impedance. |
| 4 (OUT) | Amplifier output | Rail-to-rail capable; drives loads ≥10 kΩ directly; requires external pull-down if high-Z state needed during shutdown. |
| 5 (SHDN) | Active-low shutdown control | Pulled high (≥1.5 V at 1.8 V supply) for normal operation; driven low (≤0.2 V) to enter ultra-low-power shutdown mode. |
| 6 (V+) | Positive supply rail | Accepts 1.5–5.5 V; bypass capacitor (0.1 μF ceramic) required adjacent to pin to suppress supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 1 pA typical - eliminates voltage errors in MΩ-range sensor interfaces (e.g., electrochemical sensors, photodiodes). |
| Rail-to-rail output swing | 7 mV from rails at 10 kΩ - preserves full ADC input range in 1.8 V and 3.3 V systems without supply headroom overhead. |
| Low shutdown current | 10 pA typical - enables microcontroller-gated operation with no measurable impact on system standby budget. |
| Wide common-mode input range | –0.2 V to V+ – 0.5 V - supports direct connection to ground-referenced sources and single-supply signal chains. |
| Fast wake-up from shutdown | 5 μs typical turnon time - suitable for burst-mode sampling in data loggers and event-triggered monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV341AIDCKR | A-grade variant with tighter 1.25 mV max offset (vs. standard grade's 4 mV max) at 25°C; otherwise identical electrical and pinout specs. | Required for DC-coupled precision applications demanding <0.5 mV offset drift over temperature. | Select TLV341AIDCKR when absolute DC accuracy outweighs cost sensitivity; otherwise TLV341IDCKR suffices for AC-coupled or moderate-precision use. |
| OPA316IDBVR | Higher 10 MHz GBW, lower 11 nV/√Hz input noise, but 250 μA supply current and no shutdown pin; SOT-23-5 (no SHDN) vs. SC70-6. | Suitable for higher-speed signal chains (e.g., active filters >500 kHz) where shutdown is unnecessary and board area permits larger current draw. | Choose OPA316IDBVR only when bandwidth or noise performance is prioritized over power and feature parity; not drop-in replaceable due to missing SHDN and different pin count. |
Compared with TLV341AIDCKR, the TLV341IDCKR trades guaranteed low-offset performance for broader availability and lower unit cost in volume production; versus OPA316IDBVR, it delivers 3.5× lower quiescent current and integrated shutdown at the expense of bandwidth and noise floor - making it optimal for always-on, battery-limited endpoints.

FAQ
What is the maximum supply voltage rating for TLV341IDCKR?
The absolute maximum supply voltage for TLV341IDCKR is 5.5 V. Operation above this level risks permanent damage. Recommended operating range is 1.5 V to 5.5 V, with full specifications guaranteed across this span. At 5 V supply, the device delivers 2.3 MHz gain bandwidth and 1 V/μs slew rate - confirming robust performance at upper rail limits.
Does TLV341IDCKR support true rail-to-rail input?
TLV341IDCKR supports rail-to-rail *output* swing (within 7 mV of V+ and GND), but its input common-mode range extends from –0.2 V to V+ – 0.5 V - meaning it accepts inputs down to 0.2 V below ground and up to 0.5 V below V+, but not full rail-to-rail input. This allows ground-referenced operation and compatibility with most single-supply sensor outputs.
How does the shutdown function behave on TLV341IDCKR?
TLV341IDCKR enters shutdown when the SHDN pin is pulled low (≤0.2 V); in this state, supply current drops to 10 pA typical and the output becomes high-impedance. Normal operation resumes within 5 μs after SHDN is raised to ≥1.5 V (at 1.8 V supply). The pin is CMOS-compatible and requires no external pull-up for basic functionality.
Is TLV341IDCKR suitable for driving ADC inputs directly?
Yes - TLV341IDCKR is well-suited for driving SAR and delta-sigma ADC inputs. Its rail-to-rail output swing (7 mV from rails), low output impedance, and 2.3 MHz bandwidth allow clean settling into typical 10 kΩ–100 kΩ ADC input impedances. For 12-bit+ accuracy, pairing with the A-grade TLV341AIDCKR further minimizes offset-induced code errors.
What package type is used for TLV341IDCKR?
TLV341IDCKR uses the SC70-6 (DCK) package: a 6-pin surface-mount outline measuring 2.00 mm × 1.25 mm with 0.65 mm pitch. This ultra-compact footprint is ideal for space-constrained applications like hearing aids, wearables, and miniature sensor modules - and is distinct from the SOT-23-6 (DBV) and SOT-23-6 (DRL) variants of the same device family.
