Texas Instruments TLV333IDBVT

Overview

TLV333IDBVT from Texas Instruments is a single-channel, zero-drift CMOS operational amplifier optimized for precision, low-voltage, low-power applications. It delivers 2 µV max input offset voltage, 0.02 µV/°C drift, 17 µA quiescent current, and rail-to-rail input/output swing across 1.8 V to 5.5 V supply - enabling high-accuracy signal conditioning in battery-powered medical sensors and portable instrumentation.

For engineers reviewing the TLV333IDBVT datasheet, TLV333IDBVT pinout, TLV333IDBVT application, or TLV333IDBVT equivalent, key selection considerations include its ultra-low 1.1 µV_PP (0.1–10 Hz) noise, internal EMI filtering, SC70-5 package footprint, and guaranteed operation from –40°C to +125°C in space-constrained, thermally variable environments.

Technical Context

The TLV333IDBVT employs a proprietary auto-calibration architecture with continuous 125-kHz correction cycles every 8 µs, eliminating 1/f flicker noise while maintaining unity-gain stability and no output phase reversal. Its input stage extends 0.1 V beyond both supply rails, and the output swings within 30 mV of each rail under load.

This op amp integrates internal EMI filtering (≈8 MHz cutoff, 20 dB/decade roll-off) on both common-mode and differential inputs, and features high PSRR (102–115 dB) and CMRR (102–115 dB), making it suitable for direct battery-sourced circuits without regulation where supply ripple and environmental noise are present.

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage for TLV333IDBVT?

The absolute maximum supply voltage for TLV333IDBVT is 7 V across V+ and V– terminals. Operating above this - even momentarily - can cause permanent damage. The device is specified for reliable operation between 1.8 V and 5.5 V, with optimal precision performance observed at 3.3 V and 5 V supplies. Always use 0.1-µF ceramic bypass capacitors close to the V+ and V– pins to suppress supply transients that could approach the 7-V limit.

Does TLV333IDBVT support rail-to-rail input and output simultaneously?

Yes, TLV333IDBVT supports true rail-to-rail input and output operation. Its input common-mode range extends from (V–) – 0.1 V to (V+) + 0.1 V, and its output swings to within 30 mV of both rails under 10-kΩ load at 25°C. This simultaneous RRO capability enables full utilization of ADC reference voltage in single-supply systems - for example, delivering 0–3.3 V output from a 3.3-V supply when amplifying a 0–100-mV thermistor signal.

How does the auto-calibration in TLV333IDBVT affect system timing?

TLV333IDBVT performs internal auto-calibration every 8 µs using a time-continuous 125-kHz auxiliary amplifier, with no interruption to signal path continuity. Power-up settling to full V_OS accuracy requires ≈100 µs. This architecture introduces no aliasing or step artifacts - unlike chopper-stabilized amplifiers with discrete switching - making TLV333IDBVT suitable for continuous-sampling data acquisition where timing jitter or transient glitches must be avoided.

Can TLV333IDBVT drive capacitive loads without oscillation?

TLV333IDBVT is unity-gain stable and characterized to drive ≥100 pF capacitive loads without external compensation, as confirmed in Figure 14 of the SBOS751 datasheet. For loads >100 pF (e.g., long traces or ADC input capacitance), a small series resistor (10–50 Ω) between amplifier output and load is recommended to maintain phase margin. Avoid direct connection to >500-pF loads without isolation, as this may degrade settling time and increase overshoot beyond 0.01%.

Is TLV333IDBVT qualified for automotive applications?

TLV333IDBVT is specified for operation from –40°C to +125°C and meets JEDEC JESD22-A108 reliability standards, but it is not AEC-Q200 qualified. It is suitable for under-hood industrial sensors and commercial-grade automotive accessories (e.g., cabin air quality monitors), but not for safety-critical ADAS or powertrain control units requiring AEC-Q100 qualification. For automotive-grade alternatives, consider TI's TLV333-Q1 variant, which undergoes full AEC-Q100 stress testing.
