Texas Instruments TLV341IDBVR

Overview

TLV341IDBVR from Texas Instruments is a single-channel, low-voltage, rail-to-rail output CMOS operational amplifier with active-low shutdown control, designed for 1.5V–5.5V single-supply operation. It delivers 2.3MHz gain bandwidth, 0.9V/μs slew rate, 70μA/channel quiescent current, 1.25mV max input offset (A grade), and rail-to-rail output swing within 7mV of V+ and 14mV of GND at 10kΩ load - enabling precision signal conditioning in battery-powered audio preamplifiers and supply monitoring circuits.

For engineers reviewing the TLV341IDBVR datasheet, TLV341IDBVR pinout, TLV341IDBVR application, or TLV341IDBVR equivalent, key selection criteria include ultra-low 1pA typical input bias current, 5μs typical wake-up time from shutdown, –40°C to 125°C extended industrial temperature range, and SOT-23-6 package compatibility with space-constrained portable designs.

Technical Context

The TLV341IDBVR uses a PMOS input stage to achieve rail-to-rail common-mode input range (–0.2V to V+ – 0.5V) and ultra-low input bias current (1pA typ). Its CMOS output stage enables true rail-to-rail output swing with <25mV headroom at 10kΩ load across temperature.

Shutdown functionality is implemented via an active-low SHDN pin that reduces supply current to 10pA typical per channel while placing the output in high-impedance state; turn-on time is 5μs typical, supporting rapid power cycling in energy-sensitive systems.

FAQ

What is the maximum supply voltage rating for TLV341IDBVR?

The absolute maximum supply voltage for TLV341IDBVR is 5.5V. Operation above this level risks permanent damage per Section 5.1 of the datasheet. Recommended operating range is 1.5V to 5.5V, with stable performance verified at 1.8V and 5V nominal supplies. Always use a 0.1μF ceramic bypass capacitor directly at the V+ pin to prevent transient overvoltage events.

Does TLV341IDBVR support true rail-to-rail input common-mode range?

TLV341IDBVR supports a wide input common-mode range from –0.2V to (V+ – 0.5V), which includes ground but does not extend to the positive rail. This PMOS-input architecture enables ground-referenced sensing without external level shifting, though inputs exceeding V+ – 0.5V may cause phase reversal or increased offset. The TLV341IDBVR datasheet specifies CMRR ≥60dB within this range at 25°C.

How does the shutdown function behave on TLV341IDBVR?

When the SHDN pin is driven low (<0.2V), TLV341IDBVR enters shutdown mode with supply current reduced to 10pA typical per channel and output placed in high-impedance state. Normal operation resumes within 5μs typical after SHDN is raised above the threshold (≥1.5V at 1.8V supply, ≥4.5V at 5V supply). The TLV341IDBVR output remains floating - external pull-up/down resistors may be needed for defined logic states in downstream circuitry.

What is the typical input voltage noise of TLV341IDBVR at 10kHz?

The TLV341IDBVR exhibits 20nV/√Hz typical input voltage noise at 10kHz, as specified in the Features section and confirmed in Figure 5-18 of the datasheet. This value remains stable across 1.8V and 5V supplies and is representative of its CMOS input stage. At 1kHz, noise rises to 33nV/√Hz, indicating low 1/f noise corner - beneficial for audio and sensor signal chains where mid-band noise dominates total integrated noise.

Is TLV341IDBVR pin-compatible with other SOT-23-6 op-amps like MCP6001 or LMV321?

No, TLV341IDBVR is not pin-compatible with MCP6001 or LMV321. While all three use SOT-23-6 packages, TLV341IDBVR assigns Pin 5 to SHDN (active-low), whereas MCP6001 uses Pin 5 for output and LMV321 uses Pin 5 for NC or shutdown depending on variant. Substituting without board revision risks incorrect biasing or non-functional shutdown. Always verify pin functions using Table 4-1 in the TLV341IDBVR datasheet before replacement.
