Product details
Overview
TLV341IDCKT from Texas Instruments is a single-channel, low-voltage, rail-to-rail output CMOS operational amplifier with active-low shutdown control, specified for 1.5V to 5.5V operation. It delivers 2.3MHz gain bandwidth, 0.9V/μs slew rate, and ultra-low 70μA/channel supply current - enabling precision signal conditioning in space-constrained, battery-powered systems such as portable audio preamplifiers and supply current monitors.
For engineers reviewing the TLV341IDCKT datasheet, TLV341IDCKT pinout, TLV341IDCKT application, or TLV341IDCKT equivalent, key selection criteria include its 1pA typical input bias current, 1.25mV max offset (A grade), rail-to-rail output swing down to 7mV from rails (at 10kΩ load), 5μs turnon time from shutdown, and SC70-6 package compatibility with high-density PCB layouts.
Technical Context
The TLV341IDCKT employs a PMOS input stage enabling common-mode input range from –0.2V to (V+ – 0.5V), including ground reference, and a CMOS output stage supporting true rail-to-rail swing. Its shutdown function reduces supply current to 10pA (typical) per channel while placing the output in high-impedance state.
Designed for single-supply operation, it maintains stable performance across –40°C to +125°C and supports 1.8V/5V dual-voltage characterization. The device exhibits 20nV/√Hz input voltage noise at 10kHz and meets JESD22 ESD ratings of ±2000V HBM and ±750V CDM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V - enables direct integration into Li-ion, coin-cell, and USB-powered systems without level-shifting. |
| Gain Bandwidth Product | 2.3MHz (typ) - supports stable closed-loop operation up to ~200kHz with unity-gain stability into 200pF capacitive loads. |
| Input Bias Current | 1pA (typ) - minimizes DC error in high-impedance sensor interfaces (e.g., photodiode transimpedance amps). |
| Output Swing | 7mV from V+ and 14mV from GND (at 10kΩ, 25°C) - preserves dynamic range in low-voltage ADC driver and buffer applications. |
| Shutdown Current | 10pA (typ) per channel - extends battery life in intermittent-sensing systems (e.g., wearable health monitors). |
| Turnon Time (SHDN) | 5μs (typ) - allows rapid wake-up for event-triggered signal acquisition without compromising power savings. |
| Input Offset Voltage | 1.25mV max (A grade, 25°C) - ensures ≤0.025% gain error in 50mV full-scale current-sense amplifiers. |
Pinout & Package
TLV341IDCKT is packaged in a 6-pin SC70 (DCK) footprint measuring 2.00mm × 1.25mm, optimized for ultra-compact PCB layouts. Pin functions are validated per TI SLVS568E Rev. July 2025.
| Pin/Terminal | Circuit Role | Design Meaning |

| 1 (IN+) | Noninverting input | Accepts analog signals from 0.2V below GND to V+ – 0.5V; compatible with ground-referenced sensors. |
| 2 (GND) | Ground reference | Primary return path for supply and signal currents; must be low-impedance for noise immunity. |
| 3 (IN−) | Inverting input | Differential input node; used with feedback network to set closed-loop gain and bandwidth. |
| 4 (OUT) | Amplifier output | Rail-to-rail CMOS output capable of sourcing/sinking ≥6mA; high-Z during shutdown. |
| 5 (SHDN) | Active-low shutdown control | Pulled high (>1.5V at 1.8V V+) to enable; driven low (≤0.2V) to enter ultra-low-power mode. |
| 6 (V+) | Positive supply | Single supply input (1.5–5.5V); bypass capacitor (0.1μF ceramic) required adjacent to this pin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6001T-I/OT | Higher 100μA supply current; no shutdown pin; 1MHz GBW; 2.7–5.5V only. | Lacks low-power shutdown and sub-2V operation - unsuitable for coin-cell or 1.8V logic systems. | Select when shutdown and ultra-low voltage are not required, and cost sensitivity outweighs power/performance trade-offs. |
| OPA316IDBVR | Lower 10nV/√Hz noise; 10MHz GBW; 2.7–5.5V; no shutdown; 100μA ICC. | Superior AC performance but incompatible with 1.5–2.5V battery chemistries and missing power-gating capability. | Prefer for high-fidelity audio or wideband sensor signal chains where supply voltage ≥2.7V and continuous operation is mandatory. |
Compared with MCP6001T-I/OT and OPA316IDBVR, TLV341IDCKT uniquely combines 1.5V operation, integrated shutdown, and sub-100μA quiescent current - making it the only viable option for always-on, multi-year battery life designs in sub-2V embedded systems.

FAQ
What is the maximum operating supply voltage for TLV341IDCKT?
The absolute maximum supply voltage for TLV341IDCKT is 5.5V. Operation above this level risks permanent damage. The recommended operating range is 1.5V to 5.5V, with full electrical specifications guaranteed across that span. At 5V, TLV341IDCKT achieves 2.3MHz GBW and 1V/μs slew rate, while maintaining 1.25mV max input offset voltage in A-grade units.
Does TLV341IDCKT support true rail-to-rail input common-mode range?
TLV341IDCKT supports a wide input common-mode range from –0.2V to (V+ – 0.5V), which includes ground but does not extend fully to the positive rail. This PMOS-input architecture enables accurate sensing of signals referenced to GND in single-supply systems. For applications requiring input beyond V+ – 0.5V, an external level-shifter or alternative amplifier with complementary input stage is required.
How does the shutdown feature affect output behavior in TLV341IDCKT?
When the SHDN pin is pulled low (≤0.2V), TLV341IDCKT enters shutdown mode: supply current drops to 10pA (typical), and the output transitions to a high-impedance (Hi-Z) state - electrically disconnecting from the load. This prevents back-driving or loading downstream circuitry. The output remains Hi-Z until SHDN rises above the threshold (~1.5V at 1.8V V+), after which normal operation resumes in 5μs (typical).
Can TLV341IDCKT drive capacitive loads up to 200pF while maintaining stability?
Yes, TLV341IDCKT is characterized for stability with 200pF capacitive loads at unity gain (RL = 10kΩ), exhibiting ≥55° phase margin and ≥15dB gain margin per TI SLVS568E. This makes it suitable for driving ADC input capacitors, long PCB traces, or filter stages without external compensation. For loads >200pF, a series isolation resistor (e.g., 10–50Ω) between OUT and the capacitive node is recommended to preserve phase margin.
What is the guaranteed input offset voltage specification for TLV341IDCKT over temperature?
TLV341IDCKT (A grade) guarantees a maximum input offset voltage of 1.7mV over the full operating temperature range of –40°C to +125°C. At 25°C, the limit is tighter: 1.25mV max. This drift is supported by a typical temperature coefficient of 1.9μV/°C, ensuring predictable DC error accumulation in precision instrumentation and closed-loop control applications.
