Product details
Overview
TLV2432AID from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 10 V), low-power operation. It delivers 950 µV max input offset voltage (TA = 25°C), 18 nV/√Hz input voltage noise at 1 kHz, and 125 µA per channel supply current - enabling precision signal conditioning in battery-powered sensor interfaces and ADC drivers.
For engineers reviewing the TLV2432AID datasheet, TLV2432AID pinout, TLV2432AID application, or TLV2432AID equivalent, key selection criteria include its extended common-mode input range (0 V to 4.5 V on 5 V supply), no phase inversion behavior near rails, and 600 Ω output drive capability for telecom-grade load handling.
Technical Context
The TLV2432AID uses CMOS input stage architecture with Class AB output stage, supporting true rail-to-rail output swing while maintaining stability into 2 kΩ loads with 100 pF capacitive load. Its input common-mode range extends to within 0.25 V of V– and V+, eliminating phase reversal when driven to supply rails - a critical advantage over standard CMOS op-amps in single-supply transducer interfaces.
It operates across –40°C to +85°C (I-suffix), is fully characterized at 3 V and 5 V supplies, and features 1000 GΩ differential and common-mode input resistance with only 8 pF input capacitance - preserving high-impedance source integrity in piezoelectric and pH sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports direct integration into Li-ion (3.7 V nominal) and USB-powered systems without LDO regulation. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables <1 LSB error in 12-bit ADC interfacing with 3 V reference. |
| Supply Current (per channel) | 150 µA max - allows >1-year battery life in coin-cell–powered IoT nodes with 10 µA sleep current budget. |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - preserves SNR in low-level audio preamplifiers and strain-gauge bridges. |
| Common-Mode Input Range | 0 V to 4.5 V (min) on 5 V supply - accommodates ground-referenced sensors without level-shifting circuitry. |
| Output Drive Capability | 600 Ω load - drives telecom line-interface circuits and SAR ADC sample-and-hold inputs directly. |
| Gain-Bandwidth Product | 0.55 MHz at 5 V - sufficient for anti-aliasing filters up to ~50 kHz with unity-gain stability. |
Pinout & Package
TLV2432AID is housed in an 8-pin SOIC (D package), 3.9 mm × 4.9 mm body, 1.27 mm pitch, with exposed pad not present. Pinout validated per TI SLOS168G Figure 3-1 (D package top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (–IN) | Differential input node; high-impedance (1000 GΩ) CMOS input for precision feedback networks. |
| 2 | Non-Inverting Input (+IN) | Differential input node; same impedance and noise performance as Pin 1; accepts signals down to V–. |
| 3 | Output A | Rail-to-rail output capable of sourcing/sinking ±3 mA into 600 Ω load at full swing. |
| 4 | V– (Ground / Negative Supply) | Reference return for dual-supply operation or ground connection in single-supply configurations. |
| 5 | Non-Inverting Input B (+IN) | Second amplifier's positive input; electrically isolated from Channel A; identical specs and layout symmetry. |
| 6 | Inverting Input B (–IN) | Second amplifier's negative input; supports independent gain-setting resistors per channel. |
| 7 | Output B | Independent rail-to-rail output; no crosstalk specification given, but layout separation minimizes inter-channel coupling. |
| 8 | V+ (Positive Supply) | Single or positive rail connection; supports up to 12 V absolute max, but rated for 2.7–10 V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 20 mV of V+ and V– at 100 µA load - maximizes dynamic range for 3 V ADCs without external charge pumps. |
| No phase inversion | Operates linearly even when common-mode input reaches V– or V+, eliminating latch-up risk in sensor biasing circuits. |
| Low input bias current | 1 pA typical - prevents significant voltage drop across >10 MΩ source impedances (e.g., pH electrodes, photodiodes). |
| Extended common-mode range | 0 V to VDD–1.3 V - enables direct interfacing with 0–5 V industrial sensors without resistor dividers. |
| Low-noise, low-power trade-off | 18 nV/√Hz at 1 kHz with only 125 µA supply - outperforms micropower op-amps (e.g., LPV821) in noise-sensitive, battery-constrained designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Higher supply current (250 µA/ch), lower VIO (120 µV max), wider GBW (5.5 MHz) | Better for high-speed, high-precision data acquisition; less suitable for ultra-low-power battery use | Select OPA2340UA when precision and bandwidth outweigh battery life requirements. |
| MCP6022-I/SN | Higher input bias current (100 pA typ), higher noise (25 nV/√Hz), same supply current (~150 µA) | Less ideal for high-impedance sources like piezoelectric sensors; cost-optimized for consumer electronics | Choose MCP6022-I/SN where cost sensitivity exceeds noise or bias current requirements. |
Compared with TLV2432AID, OPA2340UA trades 2× higher quiescent current for 8× lower offset and 11× higher bandwidth, while MCP6022-I/SN offers comparable power but sacrifices 1.4× more noise and 100× higher input bias - making TLV2432AID optimal for low-noise, low-power, high-impedance sensing where moderate speed suffices.

FAQ
What is the maximum operating temperature range for TLV2432AID?
The TLV2432AID is rated for operation from –40°C to +85°C (I-suffix grade). This industrial temperature range is confirmed in Section 4.3 "Recommended Operating Conditions" of the TI SLOS168G datasheet, and applies to both electrical performance and reliability specifications across the full supply voltage range (2.7 V to 10 V).
Does TLV2432AID support true rail-to-rail input operation?
No, TLV2432AID provides rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range extends from V– to (V+ – 1.3 V) - e.g., 0 V to 3.7 V on a 5 V supply. This is explicitly stated in the "Extended common-mode input voltage range" feature and Table 4.3, distinguishing it from full rail-to-rail input/output amplifiers like the TLV27x series.
Can TLV2432AID drive a 10 nF capacitive load stably?
TLV2432AID is characterized for stability with 100 pF capacitive load (Section 4.5, 4.9), but no data is provided for 10 nF. Driving such a large capacitance risks oscillation due to phase margin degradation. For 10 nF loads, TI recommends adding a series isolation resistor (e.g., 10–100 Ω) between TLV2432AID output and the capacitor, as outlined in Application Report SLOA020.
What is the typical input offset voltage drift over temperature for TLV2432AID?
The TLV2432AID has a temperature coefficient of input offset voltage (αVIO) of 2 µV/°C over 25°C to 70°C, as specified in Tables 4.4 and 4.8. This value is consistent across all suffixes (C/I/Q) and supply voltages (3 V and 5 V), and reflects the guaranteed maximum drift rate under normal operating conditions.
Is TLV2432AID pin-compatible with other devices in the TLV243x family?
Yes, TLV2432AID shares identical 8-pin SOIC (D package) pinout with TLV2432ID, TLV2432CD, and TLV2432AIDR - all members of the dual-channel TLV2432/TLV2432A family. Pin compatibility is confirmed in Figure 3-1 of SLOS168G and supported by TI's packaging documentation for D-package variants.
