Product details
Overview
TLV2432CDR 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 18 nV/√Hz input voltage noise at 1 kHz, 950 µV max input offset voltage (TLV2432A variant), and 125 µA per channel supply current - enabling precision signal conditioning in battery-powered sensor interfaces and ADC drivers.
For engineers reviewing the TLV2432CDR datasheet, TLV2432CDR pinout, TLV2432CDR application, or TLV2432CDR equivalent, key selection criteria include its extended common-mode input range (0 V to 4.5 V @ 5 V supply), no phase inversion behavior near rails, 600 Ω output drive capability, and SOIC-8 packaging suitable for space-constrained industrial and portable designs.
Technical Context
The TLV2432CDR employs CMOS input stage architecture with Class AB output stage, supporting rail-to-rail output swing while maintaining stable operation across full common-mode input range (0 V to VDD–1.3 V). Its input bias current of 1 pA typ enables high-impedance source interfacing without significant loading error.
It features internal compensation for unity-gain stability with 0.25 V/µs slew rate and 0.55 MHz gain-bandwidth product at 5 V supply, delivering predictable settling (6.4 µs to 0.1%) and 66° phase margin into 2 kΩ//100 pF loads - making it suitable for DC-coupled amplification and buffered analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation from Li-ion (3.3 V) up to industrial 9 V rails |
| Input Offset Voltage (max) | 950 µV - ensures ≤0.5 mV error in 5 V full-scale 12-bit ADC interface (LSB = 1.22 mV) |
| Supply Current / Channel | 150 µA max - enables >2-year battery life in 10 µA average-current portable sensors |
| Input Voltage Noise | 18 nV/√Hz @ 1 kHz - preserves SNR in low-level transducer signals (e.g., piezoelectric, thermopile) |
| Common-Mode Input Range | 0 V to 4.5 V @ 5 V supply - allows direct sensing of ground-referenced signals without level-shifting |
| Output Drive Capability | 600 Ω load - sufficient to drive SAR ADC reference buffers and active filters without external gain stages |
| Slew Rate | 0.25 V/µs - supports <100 kHz small-signal bandwidth with <0.1% distortion in unity-gain configuration |
Pinout & Package
TLV2432CDR is housed in an 8-pin SOIC (D package), 3.9 mm × 4.9 mm body, 1.27 mm pitch, with standard JEDEC MS-012AC footprint. Thermal pad not present; power dissipation rated at 725 mW at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - rail-to-rail swing (0.01 V to 4.97 V @ 5 V) drives ADC inputs or active filters |
| 2 | IN− A | Inverting input - high-impedance CMOS node (1000 GΩ) minimizes loading on high-Z sources |
| 3 | IN+ A | Non-inverting input - accepts common-mode signals from 0 V to VDD–1.3 V without phase reversal |
| 4 | V− | Negative supply or ground reference - supports single-supply (0 V) or split-supply (±2.5 V) operation |
| 5 | IN+ B | Non-inverting input of second op-amp - independent channel enables dual-sensor buffering or I/V conversion |
| 6 | IN− B | Inverting input of second op-amp - matched bias current (1 pA typ) ensures common-mode rejection in differential pairs |
| 7 | OUT B | Second amplifier output - identical rail-to-rail performance to OUT A for parallel signal paths |
| 8 | V+ | Positive supply - accepts 2.7–10 V; internal regulation enables stable operation across battery discharge curve |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full dynamic range utilization with 3.3 V or 5 V ADCs - eliminates need for level-shifting circuitry |
| No phase inversion at supply rails | Prevents catastrophic output latch-up when common-mode input reaches V− or V+, critical for sensor overvoltage tolerance |
| 1 pA typical input bias current | Supports direct connection to >100 MΩ sources (e.g., pH electrodes, photodiodes) without significant offset drift |
| 18 nV/√Hz input voltage noise | Maintains ≥70 dB SNR for 10 mVpp biomedical signals at 1 kHz, meeting ISO 13485 front-end requirements |
| 125 µA per channel supply current | Reduces quiescent power to 625 µW @ 5 V - ideal for always-on environmental monitoring nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Higher supply current (250 µA/ch), lower noise (12 nV/√Hz), same SOIC-8 package | Better for high-SNR audio preamps; less suitable for ultra-low-power battery systems | Select when noise dominates over power budget - OPA2340UA improves SNR by 3.5 dB but doubles current draw |
| MCP6022-I/SN | Higher VIO (2500 µV max), wider supply range (2.7–6 V), same pinout and 1 pA IB | Acceptable for cost-sensitive industrial controls where 0.05% linearity is sufficient | Choose for price-sensitive volume production where ±1.25 mV offset is tolerable in 5 V systems |
Compared with TLV2432CDR, OPA2340UA trades 125 µA for 12 nV/√Hz noise - optimal for signal integrity-critical designs - while MCP6022-I/SN sacrifices offset accuracy for broader qualification and lower unit cost, fitting non-precision industrial use cases.

FAQ
What is the maximum operating temperature range for TLV2432CDR?
The TLV2432CDR is specified for commercial temperature range: 0°C to +70°C. Its absolute maximum junction temperature is 150°C, and storage temperature spans –65°C to +150°C. For extended industrial operation (–40°C to +85°C), the TLV2432IDR variant is recommended - TLV2432CDR itself is not characterized or guaranteed beyond 70°C ambient.
Does TLV2432CDR support true rail-to-rail input operation?
No, TLV2432CDR provides rail-to-rail *output* swing only. Its common-mode input voltage range extends from V− to (V+ – 1.3 V) - e.g., 0 V to 3.7 V with 5 V supply. It does not accept inputs at the positive rail, unlike rail-to-rail input amplifiers such as the TLV2462. This design avoids complexity while retaining no-phase-inversion behavior near the rails.
Can TLV2432CDR drive a 10 kΩ load with rail-to-rail output?
Yes - TLV2432CDR guarantees rail-to-rail output swing into loads ≥600 Ω. With a 10 kΩ load, output swing improves further: VOH = 4.97 V and VOL = 0.01 V at 5 V supply (25°C), exceeding 99.8% of full scale. The 600 Ω rating ensures performance under worst-case conditions including temperature extremes and process variation.
How does the input offset voltage of TLV2432CDR compare to TLV2432A variants?
TLV2432CDR is the standard-grade version with 2000 µV max VIO at 25°C; TLV2432ACDR is the precision A-grade variant with 950 µV max VIO at 25°C. Both share identical pinout, package, and electrical characteristics except for offset voltage and its temperature coefficient (2 µV/°C for both). TLV2432CDR meets general-purpose requirements; TLV2432ACDR targets higher-accuracy systems like precision data acquisition.
Is TLV2432CDR compatible with lead-free reflow profiles?
Yes - TLV2432CDR in SOIC-8 (D package) is qualified for lead-free soldering per JEDEC J-STD-020 Rev. E, with peak reflow temperature up to 260°C for 30 seconds. Moisture sensitivity level is MSL-1 (unlimited floor life), and the device undergoes 100% post-assembly burn-in testing per TI's automotive-grade reliability standards.
