Product details
Overview
TLV8801DBVR from Texas Instruments is a single-channel nanopower operational amplifier designed for ultra-low-power sensing in battery-constrained systems. It delivers 320 nA typical supply current, 4.5 mV max offset voltage, rail-to-rail output swing within 3.5 mV of rails at 1.8 V, and operates from 1.7 V to 5.5 V. It is used in electrochemical gas sensors (e.g., CO detectors) where femtoamp input bias current and EMI immunity preserve signal integrity.
For engineers reviewing the TLV8801DBVR datasheet, TLV8801DBVR pinout, TLV8801DBVR application, or TLV8801DBVR equivalent, key selection criteria include guaranteed 320 nA quiescent current per channel, –40°C to 125°C operation, SOT-23-5 packaging, 6 kHz unity-gain bandwidth, and verified performance in transimpedance amplifier (TIA) configurations with >1 MΩ feedback resistors.
Technical Context
The TLV8801DBVR employs a CMOS input stage enabling ≤100 fA input bias current, critical for high-impedance sensor interfaces like potentiostats and PIR motion detectors. Its input common-mode range extends to the negative rail (V–), supporting true single-supply operation without level-shifting circuitry.
Internally compensated for unity-gain stability, it achieves 6 kHz gain-bandwidth product while maintaining 120 dB open-loop gain and 87 dB CMRR at 5 V supply. Built-in EMI protection reduces susceptibility to RF interference from mobile devices and wireless transceivers-verified across 10 MHz–1 GHz band.

FAQ
What is the maximum operating supply voltage for TLV8801DBVR?
The TLV8801DBVR supports a maximum supply voltage of 6 V, as specified in its Absolute Maximum Ratings. However, its recommended operating range is 1.7 V to 5.5 V. Operating above 5.5 V risks permanent damage and violates functional specifications; designs must ensure V+ − V− does not exceed 5.5 V during normal use or transient events. The TLV8801DBVR is commonly used at 3.3 V or 1.8 V to optimize power efficiency in portable systems.
Does TLV8801DBVR support rail-to-rail input common-mode range?
No, TLV8801DBVR does not support rail-to-rail input common-mode range. Its input common-mode voltage range extends from V− to (V+) − 0.9 V. This means the non-inverting and inverting inputs operate correctly only when biased within that window-for example, 0 V to 4.1 V at a 5 V supply. The device does support rail-to-rail *output* swing, reaching within 3.5 mV of both supply rails under 100 kΩ load. This asymmetry makes TLV8801DBVR ideal for single-supply systems where the negative rail is ground but requires attention to input biasing in high-side sensing.
Can TLV8801DBVR drive capacitive loads directly?
TLV8801DBVR is unity-gain stable but becomes unstable with capacitive loads >50 pF directly connected to its output. For loads exceeding this threshold-such as ADC input capacitance or long PCB traces-an isolation resistor (RISO = 30–50 kΩ) must be placed between the TLV8801DBVR output and the capacitive node. This configuration decouples the amplifier's output impedance from the load capacitance, preserving phase margin. Without RISO, oscillation or excessive overshoot may occur, compromising signal fidelity in precision sensor applications.
Is TLV8801DBVR qualified for automotive applications?
TLV8801DBVR is specified for operation from –40°C to +125°C and meets JEDEC JESD22-A108 reliability standards, making it suitable for under-dash or cabin-mounted automotive applications such as air quality monitoring and occupant detection. However, it is not AEC-Q200 qualified. For safety-critical or engine-compartment locations requiring AEC-Q200 certification, designers should consult TI's automotive-grade alternatives. TLV8801DBVR is widely deployed in Tier-2 automotive interior modules where qualification is customer-defined rather than regulatory-mandated.
How does the EMI protection in TLV8801DBVR improve system robustness?
TLV8801DBVR integrates on-die EMI filtering that attenuates RF interference from 10 MHz to 1 GHz by ≥60 dB, validated against mobile phone, WiFi, and RFID reader emissions. This eliminates the need for external ferrite beads or RC filters in compact layouts-reducing BOM count and PCB area. In gas detector designs, this prevents false alarms triggered by RF-induced offset shifts, and in PIR systems, it maintains stable baseline output during wireless coexistence. The EMI hardening is process-intrinsic and requires no external components or layout changes to activate.
