Texas Instruments TLV2334ID

Overview

TLV2334ID from Texas Instruments is a quad low-voltage, medium-power operational amplifier in the LinCMOS™ family, designed for single-supply operation from 2 V to 8 V across –40°C to 85°C. It delivers 300 kHz unity-gain bandwidth, 0.38 V/µs slew rate (at 3 V), 10 mV max input offset voltage, and rail-to-rail output swing down to the negative rail - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.

For engineers reviewing the TLV2334ID datasheet, TLV2334ID pinout, TLV2334ID application, or TLV2334ID equivalent, key selection criteria include its 320 µA typical supply current per amplifier at 3 V, common-mode input range extending below ground, high 10¹² Ω input impedance, and compatibility with low-voltage analog front-ends in medical wearables, industrial IoT nodes, and handheld test equipment.

Technical Context

The TLV2334ID uses Texas Instruments' silicon-gate LinCMOS™ process to achieve ultra-low input bias current (0.6 pA typ at 25°C) and high input impedance, making it suitable for high-impedance source interfacing such as piezoelectric sensors and passive RC filters. Its input stage operates with common-mode voltage down to VDD–/GND and up to VDD – 1 V, supporting true single-supply signal acquisition without level-shifting circuitry.

Each of the four amplifiers features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and robust output drive capability (±30 mA). The device is fully characterized at both 3 V and 5 V, with guaranteed performance over temperature - critical for unregulated battery rails in portable systems.

FAQ

What is the minimum supply voltage for reliable operation of TLV2334ID?

The TLV2334ID is fully functional and characterized down to 2 V supply voltage across its full operating temperature range of –40°C to 85°C. At 2 V, it maintains guaranteed specifications including 300 kHz unity-gain bandwidth and 0.38 V/µs slew rate - making it suitable for deeply discharged lithium primary cells or two-cell alkaline systems. Operation below 2 V is not specified and may result in degraded AC performance or undefined behavior.

Does TLV2334ID support true rail-to-rail input operation?

The TLV2334ID supports rail-to-rail output swing on the low side (down to VDD–/GND), but its common-mode input voltage range extends only to VDD – 1 V on the high side - not full rail-to-rail input. At 3 V supply, the maximum allowable input voltage is 2 V; at 5 V, it is 4 V. This design enables robust operation with ground-referenced signals while maintaining process-related headroom for input stage biasing.

Can TLV2334ID drive capacitive loads directly, and what is the maximum stable capacitance?

The TLV2334ID is stable driving up to 20 pF capacitive load with 100 kΩ resistive load, as verified in the datasheet's Figure 34 and 36. For larger capacitive loads (e.g., ADC input capacitance >20 pF), external isolation resistance (≥500 Ω) between amplifier output and capacitor is required to maintain phase margin above 36° and prevent peaking or oscillation. No internal compensation adjustment is provided.

How does the input offset voltage of TLV2334ID vary with temperature?

The TLV2334ID has an average temperature coefficient of input offset voltage (αVIO) of 1 µV/°C (typ) to 1.7 µV/°C (max) over 25°C to 85°C. Over the full –40°C to 85°C range, total VIO drift is bounded by the 12 mV max specification - meaning worst-case offset change due to temperature is ≤12 mV, regardless of initial room-temperature value. This is confirmed in Table "TLV2334I electrical characteristics" on page 8.

Is TLV2334ID pin-compatible with other quad op-amps in SOIC-14 packages?

The TLV2334ID follows the industry-standard SOIC-14 quad op-amp pinout (1OUT, 1IN–, 1IN+, GND, 2IN+, 2IN–, 2OUT, VDD, 3OUT, 3IN–, 3IN+, GND, 4IN+, 4OUT), matching LM324, TLV2434, and LMV324 families. However, differences in input stage architecture (LinCMOS™ vs. bipolar vs. CMOS), supply voltage range, and output drive require verification of signal chain compatibility - especially regarding input common-mode range and output swing limitations.
