Product details
Overview
TLV2333IDGKT from Texas Instruments is a dual-channel, zero-drift CMOS operational amplifier optimized for precision, low-voltage, low-power applications. It delivers 2 µV typical input offset voltage, 0.02 µV/°C drift, 17 µA quiescent current per amplifier, rail-to-rail input/output, and operates from 1.8 V to 5.5 V supply. It is used in high-accuracy sensor signal conditioning circuits such as thermistor-based temperature measurement and low-side current sensing.
For engineers reviewing the TLV2333IDGKT datasheet, TLV2333IDGKT pinout, TLV2333IDGKT application, or TLV2333IDGKT equivalent, key selection criteria include ultra-low offset drift over temperature, sub-20 µA per-channel power budget, 1.8 V single-supply operation, and guaranteed performance from –40°C to +125°C in industrial and medical instrumentation.
Technical Context
The TLV2333IDGKT employs a proprietary auto-calibration architecture that corrects input offset every 8 µs using a time-continuous 125-kHz core amplifier, eliminating 1/f noise and enabling stable dc precision without output phase reversal. Its input stage features internal EMI filtering with ~8 MHz cutoff and supports common-mode voltages extending 0.1 V beyond both supply rails.
This dual op amp integrates rail-to-rail output stages capable of swinging within 30 mV of either rail at full load and achieves 350 kHz gain-bandwidth with 0.16 V/µs slew rate. It is unity-gain stable and characterized for operation across the full –40°C to +125°C industrial temperature range with 102 dB minimum open-loop gain and 102 dB minimum CMRR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 2 µV typical - enables direct amplification of µV-level sensor outputs without calibration overhead |
| Offset Drift vs Temp | 0.02 µV/°C - ensures <100 nV total drift over –40°C to +125°C, critical for unattended long-term monitoring |
| Quiescent Current | 17 µA per amplifier - allows dual-channel precision amplification in battery-powered devices with multi-year runtime |
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct connection to single-cell Li-ion, alkaline, or regulated 3.3 V/5 V rails without LDO |
| Input Voltage Range | (V–) – 0.1 V to (V+) + 0.1 V - eliminates external level-shifting for sensors referenced to ground or supply |
| Output Swing | Within 30 mV of rails at full load - preserves dynamic range in low-voltage systems where headroom is constrained |
| Gain-Bandwidth Product | 350 kHz - sufficient for anti-aliasing, sensor filtering, and DC-coupled transducer interfaces up to ~100 Hz |
Pinout & Package
VSSOP-8 package (3.00 mm × 3.00 mm body size), thermally enhanced for surface-mount assembly in space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives feedback network or downstream ADC input with rail-to-rail swing |
| 2 | –IN A | Inverting input, channel A - connects to feedback resistor or inverted sensor interface node |
| 3 | +IN A | Noninverting input, channel A - accepts high-impedance sensor signals (e.g., thermistor divider midpoint) |
| 4 | V– | Negative supply rail - tied to system ground in single-supply configurations; must be decoupled with 0.1 µF ceramic capacitor |
| 5 | +IN B | Noninverting input, channel B - independent input for second sensor path or reference buffer |
| 6 | –IN B | Inverting input, channel B - used for differential sensing or active filter configuration |
| 7 | OUT B | Amplifier B output - provides isolated signal path for dual-sensor systems or redundancy |
| 8 | V+ | Positive supply rail - accepts 1.8–5.5 V; requires local 0.1 µF bypass to minimize PSRR-induced error |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-calibrates every 8 µs to maintain ≤2 µV offset and eliminate 1/f noise - essential for dc-coupled precision measurement |
| Rail-to-rail I/O | Input extends 100 mV beyond supplies; output swings to within 30 mV of rails - maximizes usable signal range in 1.8–3.3 V systems |
| Internal EMI filtering | Integrated ~8 MHz low-pass filter on inputs - suppresses RF rectification artifacts from cellular, Wi-Fi, or switching supply noise |
| Ultra-low quiescent current | 17 µA per amplifier at 25°C, ≤28 µA over full temperature range - enables always-on sensing without compromising battery life |
| Wide temperature rating | Specified from –40°C to +125°C - qualified for under-hood automotive, industrial control, and portable medical environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | 2 µV max offset, 0.02 µV/°C drift, 17 µA IQ, same VSSOP-8 package but higher PSRR (110 dB vs 102 dB) | Better rejection of noisy supply rails; identical thermal performance and rail-to-rail I/O | Preferred when operating from unregulated battery sources with high ripple content |
| MCP6V82-E/SN | 25 µV max offset, 0.05 µV/°C drift, 22 µA IQ, SOIC-8 package only - larger footprint and higher drift | Lower cost but reduced dc precision; not rated for +125°C operation (only –40°C to +125°C with derating) | Suitable for cost-sensitive consumer applications where ±0.1°C accuracy suffices and ambient temperature stays below 85°C |
Compared with TLV2333IDGKT, OPA2333AIDR offers superior PSRR for battery-powered systems with poor regulation, while MCP6V82-E/SN trades precision and temperature range for lower unit cost in non-critical environments.

FAQ
What is the maximum operating temperature range for TLV2333IDGKT?
The TLV2333IDGKT is fully specified from –40°C to +125°C, with absolute maximum junction temperature rated at 150°C. Electrical characteristics including offset voltage, drift, and open-loop gain are guaranteed across this full industrial temperature range, making TLV2333IDGKT suitable for under-hood automotive, factory automation, and portable medical equipment where ambient temperatures exceed 85°C.
Does TLV2333IDGKT support true rail-to-rail input operation?
Yes, TLV2333IDGKT supports rail-to-rail input with a common-mode voltage range extending from (V–) – 0.1 V to (V+) + 0.1 V. This allows direct interfacing with sensors referenced to ground or supply rails without external level-shifting circuitry. The input stage uses CMOS technology with internal EMI filtering and exhibits typical input bias current of ±70 pA at 25°C, rising to ±150 pA over temperature.
Can TLV2333IDGKT operate from a 1.8 V single supply?
Yes, TLV2333IDGKT is explicitly optimized for 1.8 V to 5.5 V operation and functions correctly with a single 1.8 V supply. At 1.8 V, it maintains rail-to-rail input/output swing, 350 kHz gain-bandwidth, and 17 µA quiescent current per amplifier. Performance parameters including CMRR (102 dB min), PSRR (102 dB min), and offset drift (0.02 µV/°C) remain valid across the entire supply range, enabling direct battery connection without regulation.
What is the typical 0.1 Hz to 10 Hz noise performance of TLV2333IDGKT?
The TLV2333IDGKT delivers 1.1 µVPP integrated input voltage noise over the 0.1 Hz to 10 Hz band, a key metric for dc and low-frequency sensor applications. This low flicker-noise performance results directly from its zero-drift auto-calibration architecture, which eliminates 1/f noise components. The device also provides flat broadband noise density of 55 nV/√Hz at 1 kHz, supporting both precision dc and moderate-bandwidth signal conditioning.
Is TLV2333IDGKT pin-compatible with other members of the TLVx333 family?
No, TLV2333IDGKT is not pin-compatible with TLV333 (single) or TLV4333 (quad). TLV2333IDGKT uses an 8-pin VSSOP package with dedicated dual-channel pinout (pins 1/2/3/4 for Channel A, pins 5/6/7/8 for Channel B and supplies). In contrast, TLV333 uses 5-pin SC70/SOT23 or 8-pin SOIC with different pin assignments, and TLV4333 uses 14-pin SOIC/TSSOP. Pin mapping must be verified per device-specific datasheet before board reuse.
