Product details
Overview
TLV341AIDBVTE4 from Texas Instruments is a single-channel, low-voltage, rail-to-rail output CMOS operational amplifier with active-low shutdown control, designed for precision signal conditioning in space-constrained, battery-powered systems. It delivers 2.3MHz gain bandwidth, 0.9V/μs slew rate, 1.25mV max input offset voltage (25°C, A grade), 70μA/channel supply current, and operates from 1.5V to 5.5V single supply - enabling use in portable audio preamplifiers and battery monitoring circuits.
For engineers reviewing the TLV341AIDBVTE4 datasheet, TLV341AIDBVTE4 pinout, TLV341AIDBVTE4 application, or TLV341AIDBVTE4 equivalent, key selection criteria include its ultra-low 1pA typical input bias current, 10pA typical shutdown current per channel, rail-to-rail output swing within 7mV of rails (at 10kΩ load), –40°C to 125°C extended industrial temperature range, and SC70-6 package footprint.
Technical Context
The TLV341AIDBVTE4 employs a PMOS input stage enabling common-mode input range from –0.2V to (V+ – 0.5V) and ultra-low 1pA input bias current. Its CMOS output stage supports rail-to-rail output swing down to 7mV from V+ and 14mV from GND at 10kΩ load.
It features an active-low SHDN pin that reduces supply current to 10pA typical per channel and places the output in high-impedance state; turn-on time from shutdown is 5μs typical. The device is specified across 1.5V–5.5V supply and –40°C to 125°C, with input offset voltage tightly controlled to ≤1.25mV at 25°C (A grade).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.5V to 5.5V single supply - supports direct integration into 1.8V and 3.3V logic domains without level shifting. |
| Input Offset Voltage (max) | 1.25mV at 25°C (A grade) - enables accurate DC-coupled sensing in battery voltage monitors and supply current shunt amplifiers. |
| Gain Bandwidth Product | 2.3MHz typical - sufficient for anti-aliasing filters, audio preamp stages, and closed-loop gain ≥10 up to ~200kHz. |
| Slew Rate | 0.9V/μs typical - supports clean 10kHz sine wave output at 1VPP without distortion in low-noise audio paths. |
| Supply Current per Channel | 70μA typical - allows continuous operation for >1 year on a 200mAh coin cell in always-on sensor front-ends. |
| Shutdown Current | 10pA typical per channel - reduces system standby power to negligible levels in portable equipment with periodic wake-up cycles. |
| Input Bias Current | 1pA typical - minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiode transimpedance feedback networks). |
Pinout & Package
TLV341AIDBVTE4 is packaged in a 6-pin SC70 (DBV) package measuring 2.00mm × 1.25mm, optimized for ultra-compact PCB layouts in handheld and wearable devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Noninverting input | Accepts analog signals from 0.2V below GND to 0.5V below V+; compatible with ground-referenced sensors. |
| 2 (GND) | Ground reference | Primary return path for input, output, and supply currents; must be low-impedance for noise immunity. |
| 3 (IN−) | Inverting input | Used for feedback configuration (e.g., inverting amplifier, transimpedance); matched to IN+ for common-mode rejection. |
| 4 (OUT) | Amplifier output | Rail-to-rail capable: swings within 7mV of V+ and 14mV of GND at 10kΩ load - preserves dynamic range in low-voltage systems. |
| 5 (SHDN) | Active-low shutdown control | Pull to GND to disable amplifier; output goes high-Z and ICC drops to 10pA - enables software-controlled power gating. |
| 6 (V+) | Positive supply | Accepts 1.5V–5.5V; requires local 0.1μF ceramic bypass capacitor to suppress supply noise coupling into analog signal path. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full utilization of 1.8V or 3.3V supply headroom - critical for maximizing SNR in ADC driver stages. |
| Ultra-low 1pA input bias current | Reduces voltage error across MΩ-range source impedances (e.g., thermistors, capacitive touch sensors) by >100× vs bipolar op-amps. |
| A-grade 1.25mV max VOS (25°C) | Eliminates need for external trimming in precision DC measurement paths such as battery cell voltage monitoring. |
| 5μs typical turn-on from shutdown | Supports rapid wake-up in duty-cycled applications (e.g., periodic sensor sampling) without compromising system responsiveness. |
| –40°C to 125°C operating range | Validated for under-hood automotive modules, industrial IoT edge nodes, and outdoor portable electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision, low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | Higher 10MHz GBW, 2.5V/μs slew rate, but 100μA supply current and no shutdown pin. | Better for higher-frequency signal chains (e.g., active filters >100kHz); unsuitable where shutdown or sub-100μA quiescent current is required. | Choose OPA316IDBVR only when bandwidth and speed outweigh power and control requirements. |
| LPV821DBVR | Lower 650kHz GBW, 0.25V/μs slew rate, 650nA supply current, and no shutdown - but 10μV max VOS (A grade). | Superior DC precision for nanoamp-level current sensing; insufficient for audio or moderate-speed filtering. | Choose LPV821DBVR when ultra-low offset dominates over bandwidth and shutdown functionality. |
Compared with OPA316IDBVR and LPV821DBVR, TLV341AIDBVTE4 uniquely balances 2.3MHz bandwidth, rail-to-rail operation, active shutdown, and A-grade offset in a 2.0mm × 1.25mm SC70 package - making it optimal for cost- and size-sensitive portable systems requiring both precision and power control.

FAQ
What is the maximum supply voltage rating for TLV341AIDBVTE4?
The absolute maximum supply voltage for TLV341AIDBVTE4 is 5.5V. Operation above this level risks permanent damage. The recommended operating range is 1.5V to 5.5V single supply, validated across –40°C to 125°C. TI specifies thermal derating above 5.5V is not supported, and exceeding this limit voids warranty and reliability guarantees for TLV341AIDBVTE4.
Does TLV341AIDBVTE4 support true rail-to-rail input?
TLV341AIDBVTE4 supports rail-to-rail *output* swing but not full rail-to-rail *input*. Its common-mode input voltage range extends from –0.2V to (V+ – 0.5V), meaning it accepts signals down to 0.2V below ground and up to 0.5V below V+. This includes ground-referenced inputs but excludes the positive rail - unlike true RRI op-amps. This specification is confirmed in Section 5.7 and 5.8 of the TLV341AIDBVTE4 datasheet.
What is the typical output impedance of TLV341AIDBVTE4 in shutdown mode?
In shutdown mode, TLV341AIDBVTE4 drives its output into a high-impedance (Hi-Z) state, with typical output leakage current of ±100pA. This effectively isolates the output node from the amplifier core, preventing loading of downstream circuitry. The Hi-Z behavior is explicitly documented in Section 6.3.3 and Figure 6-3 of the TLV341AIDBVTE4 datasheet, and is independent of load conditions.
Can TLV341AIDBVTE4 drive a 600Ω load at 1kHz with low THD?
Yes - TLV341AIDBVTE4 achieves 0.012% THD+N at 1kHz with 1VPP output into 600Ω at 5V supply (Section 5.8). At 1.8V supply, THD+N is 0.015% under identical conditions. This performance is enabled by its CMOS output stage and 2.3MHz GBW, making TLV341AIDBVTE4 suitable for line-driver and headphone-buffer roles in portable audio where distortion below 0.02% is required.
Is the SC70-6 package of TLV341AIDBVTE4 RoHS-compliant and lead-free?
Yes - TLV341AIDBVTE4 in the SC70-6 (DBV) package is RoHS-compliant and lead-free, as confirmed by Texas Instruments' official packaging information (SLVS568E, Section 10). The "E4" suffix denotes lead-free finish per JEDEC J-STD-020, and the device meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life at ≤30°C/85% RH.
