Product details
Overview
TLV2450CDBVR from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable applications. It delivers 220 kHz gain-bandwidth, ±10 mA output drive, and 23 µA supply current per channel while operating from 2.7 V to 6 V - enabling high dynamic range in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2450CDBVR datasheet, TLV2450CDBVR pinout, TLV2450CDBVR application, or TLV2450CDBVR equivalent, key selection criteria include shutdown functionality (16 nA/channel), rail-to-rail I/O swing within 250 mV of rails at 2.5 mA load, and guaranteed operation across 0°C to 70°C in the 6-pin SOT-23 package.
Technical Context
The TLV2450CDBVR implements a CMOS input stage with rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing, supporting full-scale signal handling in single-supply systems. Its internal architecture enables stable unity-gain operation with ≥56° phase margin into 1000 pF loads.
Shutdown control is active-low: driving SHDN ≤ 0.5 V (at VDD = 3 V) or ≤ 0.8 V (at VDD = 5 V) places the output in high-impedance state and reduces supply current to 16 nA/channel. The device is fully specified at both 3 V and 5 V across its temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports direct connection to Li-ion, 3.3 V, and 5 V rails without regulation. |
| Gain-Bandwidth Product | 220 kHz - enables stable amplification of low-frequency sensor signals (e.g., ECG, thermistor outputs) with minimal phase lag. |
| Supply Current (Active) | 23 µA/channel - allows multi-year battery life in always-on wearable monitors. |
| Supply Current (Shutdown) | 16 nA/channel - reduces quiescent power by >1400×, critical for intermittent-sampling architectures. |
| Input Offset Voltage | 20 µV (typ) - ensures <1 µV error contribution in precision 12-bit ADC front-ends with gain ≤ 100. |
| Output Drive | ±10 mA - drives 2.5 mA loads while maintaining rail-to-rail swing, sufficient for driving SAR ADC reference buffers or LED bias circuits. |
| PSRR | 106 dB - rejects supply noise in noisy mixed-signal environments (e.g., shared LDO with digital ICs). |
Pinout & Package
TLV2450CDBVR is housed in a 6-pin SOT-23 package (DBV), measuring 2.9 mm × 1.6 mm × 1.15 mm, with gull-wing leads and RoHS-compliant matte tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; high-impedance during shutdown. |
| 2 (GND) | Analog ground reference | Return path for input bias current and output load; must be low-impedance for PSRR integrity. |
| 3 (IN+) | Non-inverting input | CMOS input with 0.3–4.5 nA bias current; accepts signals from 0 V to VDD. |
| 4 (VDD+) | Positive supply | Accepts 2.7–6 V; decoupling capacitor (0.1 µF) required within 2 mm for stability. |
| 5 (IN−) | Inverting input | Differential input node; matched to IN+ for low offset and drift. |
| 6 (SHDN) | Shutdown control | Active-low logic input; pulls to GND to enable shutdown mode (16 nA IDD). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of supply voltage in single-supply systems, maximizing SNR in 3 V data acquisition channels. |
| Ultralow 23 µA supply current | Permits integration into energy-harvesting nodes or coin-cell-powered devices with >5-year runtime. |
| 16 nA shutdown current | Supports duty-cycled operation where amplifier is active only during sensor sampling windows. |
| 220 kHz GBW at 23 µA | Outperforms competing micropower op-amps (e.g., LPV821) by >2× bandwidth per µA, reducing settling time in multiplexed sensor arrays. |
| Specified from 0°C to 70°C | Guarantees performance in commercial-grade portable equipment without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPV821DBVR | Lower supply current (650 nA), lower GBW (5.5 kHz), no shutdown pin. | Suitable only for sub-10 Hz DC-coupled sensing (e.g., pH probes); lacks drive strength and speed for multiplexed or AC-coupled biosignals. | Select when ultra-low IQ dominates over bandwidth and output drive requirements. |
| TLV9001SIDBVR | Higher supply current (60 µA), higher GBW (1 MHz), rail-to-rail I/O, no shutdown. | Better for higher-speed sensor interfaces (e.g., ultrasonic distance sensing), but increases battery load 2.6× vs TLV2450CDBVR. | Select when system requires >100 kHz closed-loop bandwidth and can accommodate higher quiescent power. |
Compared with LPV821DBVR and TLV9001SIDBVR, TLV2450CDBVR uniquely balances micropower operation (23 µA), usable bandwidth (220 kHz), and integrated shutdown - making it optimal for battery-constrained, medium-bandwidth analog front-ends where power cycling is essential.

FAQ
What is the maximum operating supply voltage for TLV2450CDBVR?
The absolute maximum supply voltage for TLV2450CDBVR is 7 V, but the recommended operating range is 2.7 V to 6 V. Operation above 6 V risks permanent damage and violates the device's qualified specifications. At 6 V, TLV2450CDBVR maintains full rail-to-rail output swing and 220 kHz gain-bandwidth, consistent with its datasheet characterization.
Does TLV2450CDBVR support true rail-to-rail input and output operation?
Yes, TLV2450CDBVR supports true rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 250 mV of each rail at 2.5 mA load). This is confirmed in the datasheet's "Rail-To-Rail Input/Output (RRIO)" feature list and electrical characteristics tables for VOH/VOL across 3 V and 5 V supplies.
How does the shutdown function work on TLV2450CDBVR?
The SHDN pin (Pin 6) is active-low: pulling it ≤ 0.5 V (at VDD = 3 V) or ≤ 0.8 V (at VDD = 5 V) disables the amplifier core and places the output in high-impedance state, reducing supply current to 16 nA/channel. Release to VDD re-enables operation with 59 µs turn-on time, as measured in the operating characteristics table.
What is the typical input offset voltage of TLV2450CDBVR and how does it affect precision designs?
The typical input offset voltage of TLV2450CDBVR is 20 µV at 25°C, with a maximum of 1300 µV over the full 0°C to 70°C range. In a 12-bit, 3 V ADC system with gain = 100, this contributes ≤ 0.4 LSB of error - making TLV2450CDBVR suitable for moderate-precision sensor interfaces where calibration is feasible but zero-drift op-amps are unnecessary.
Is TLV2450CDBVR compatible with standard SOT-23 PCB footprints?
Yes, TLV2450CDBVR uses the industry-standard 6-pin SOT-23 (DBV) package with 0.95 mm pin pitch and defined land pattern per JEDEC MO-178. Its footprint matches common SOT-23-6 layouts used for devices like LMV321IDBVR or OPA316IDBVR, enabling drop-in replacement in existing designs without layout revision.
