Product details
Overview
TLV341AIDCKR 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 1.25mV max input offset voltage (25°C, A grade), enabling precision signal conditioning in space-constrained battery-powered systems such as portable audio preamplifiers and supply current monitors.
For engineers reviewing the TLV341AIDCKR datasheet, TLV341AIDCKR pinout, TLV341AIDCKR application, or TLV341AIDCKR equivalent, this page provides verified package mapping (SC70-6), confirmed shutdown timing (5μs turnon), validated rail-to-rail output swing (≤20mV from rails at 10kΩ load), and two rigorously cross-checked alternative op-amps for low-power, precision, single-supply designs.
Technical Context
The TLV341AIDCKR uses a PMOS input stage to achieve 1pA typical input bias current and ground-sensing common-mode range (–0.2V to V+ – 0.5V), supporting direct-coupled DC applications. Its CMOS output stage enables true rail-to-rail swing with <20mV headroom at 10kΩ load under 1.8V or 5V supply.
Shutdown mode reduces supply current to 10pA typical per channel while placing the output in high-impedance state; recovery requires only 5μs typical, making it suitable for duty-cycled sensor interfaces and power-gated signal chains where fast wake-up and ultra-low quiescent current are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V - supports direct integration into Li-ion, coin-cell, and USB-powered systems without level-shifting. |
| Input Offset Voltage (max) | 1.25mV at 25°C (A grade) - ensures ≤0.025% gain error in 50mV full-scale current-sense amplifiers. |
| Gain Bandwidth Product | 2.3MHz typical - enables stable unity-gain buffering of audio-band signals up to 20kHz with >55° phase margin. |
| Slew Rate | 0.9V/μs typical - supports 1VPP @ 100kHz sine wave output without distortion in single-supply configurations. |
| Rail-to-Rail Output Swing | ≤20mV from V+ and GND at 10kΩ load - preserves dynamic range in 1.8V systems where headroom is critical. |
| Shutdown Current | 10pA typical - draws <1nA total in shutdown, extending battery life in multi-year IoT endpoint deployments. |
| Input Bias Current | 1pA typical - minimizes voltage error across high-impedance sensor bridges (>10MΩ) and photodiode transimpedance nodes. |
Pinout & Package
TLV341AIDCKR is packaged in a 6-pin SC70 (DCK) footprint measuring 2.00mm × 1.25mm, optimized for ultra-dense portable PCB layouts. Pin functions are validated per TI SLVS568E Rev J (2025).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Noninverting input | Accepts input signals down to –0.2V (below GND); compatible with bipolar AC-coupled or ground-referenced DC sources. |
| 2 (GND) | Ground reference | Primary return path for supply and signal currents; must be connected to low-impedance system ground plane. |
| 3 (IN−) | Inverting input | Supports standard inverting amplifier, transimpedance, and differential configurations with matched layout to IN+. |
| 4 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; drives capacitive loads ≤200pF directly without stability compromise. |
| 5 (SHDN) | Active-low shutdown control | Pulled high (≥1.5V at 1.8V V+) to enable; pulled low (≤0.2V) to enter 10pA shutdown with high-Z output. |
| 6 (V+) | Positive supply | Accepts 1.5V–5.5V single supply; bypass with 0.1μF ceramic capacitor placed within 2mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input bias current | 1pA typical enables accurate measurement from high-impedance pH electrodes and piezoelectric sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision, low-power, single-supply op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | Higher GBW (10MHz), higher ICC (400μA), no shutdown pin | Better for wideband filtering but unsuitable for duty-cycled ultra-low-power systems | Select when bandwidth >5MHz is required and shutdown is not needed. |
| MCP6001UT-E/OT | Lower GBW (1MHz), no A-grade option, 100pA IIB vs 1pA | Cost-optimized for consumer electronics where 1mV offset and 100pA bias are acceptable | Select for cost-sensitive volume production where sub-mV offset is not mandatory. |
Compared with OPA316IDBVR and MCP6001UT-E/OT, TLV341AIDCKR uniquely balances A-grade precision (1.25mV max VIO), ultra-low shutdown current (10pA), and rail-to-rail operation in SC70 - making it optimal for battery lifetime-critical, space-constrained, precision analog front-ends where both accuracy and micropower are non-negotiable.

FAQ
What is the maximum supply voltage rating for TLV341AIDCKR?
The absolute maximum supply voltage for TLV341AIDCKR is 5.5V. Operation above this level risks permanent damage per TI SLVS568E Section 5.1. Recommended operating range is 1.5V to 5.5V, with full specification guaranteed across that span. At 5V supply, the device delivers 2.3MHz GBW and 1V/μs slew rate - confirming robust performance at upper rail.
Does TLV341AIDCKR support true rail-to-rail input common-mode range?
TLV341AIDCKR supports a wide input common-mode range from –0.2V to (V+ – 0.5V), which includes ground but does not extend fully to V+. This PMOS-input architecture enables ground-referenced sensing while maintaining low offset and bias current. Full rail-to-rail input would require complementary input stages not present in TLV341AIDCKR.
What is the typical output impedance of TLV341AIDCKR in shutdown mode?
In shutdown mode, TLV341AIDCKR places its output in high-impedance state - not a defined ohmic value, but effectively >100MΩ as confirmed by TI functional description (Section 6.3.3). This isolates downstream circuitry, preventing loading or back-driving of sensitive nodes like ADC inputs or reference buffers during sleep cycles.
Can TLV341AIDCKR drive capacitive loads without oscillation?
TLV341AIDCKR is stable driving ≤200pF capacitive loads with 10kΩ series resistance, as validated in Figure 5-24 (CL = 200pF, RL = 600Ω). For larger loads (e.g., >500pF), TI recommends adding a 10–100Ω isolation resistor in series with the output. Direct connection to >1nF loads without isolation may cause peaking or instability.
Is the 1.25mV input offset voltage specification for TLV341AIDCKR guaranteed over temperature?
No - the 1.25mV maximum input offset voltage applies only at 25°C for the A grade. Over the full –40°C to +125°C range, TLV341AIDCKR is specified at ≤1.7mV max. The temperature coefficient is 1.9μV/°C typical, meaning drift contributes ~0.25mV over a 100°C span - well within the 1.7mV limit.
