Product details
Overview
TLV2450ID from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, ±10 mA output drive, 23 µA supply current per channel, and operates from 2.7 V to 6 V - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2450ID datasheet, TLV2450ID pinout, TLV2450ID application, or TLV2450ID equivalent, key selection criteria include shutdown current (16 nA), rail-to-rail I/O swing at 3 V, input offset voltage (20 µV typ), and guaranteed operation across −40°C to 125°C industrial temperature range.
Technical Context
The TLV2450ID implements a CMOS input stage with rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 250 mV of rails at 2.5 mA load). Its internal architecture supports stable unity-gain operation with phase margin ≥56° into 1000 pF capacitive loads.
Shutdown functionality is controlled by a dedicated SHDN pin that 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, with PSRR of 106 dB and CMRR of 80 dB (typ) under standard conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct interface with Li-ion, coin-cell, and 3.3 V/5 V logic systems without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - supports stable DC-coupled amplification and low-frequency sensor signal conditioning up to ~100 kHz. |
| Supply Current (per channel) | 23 µA - allows multi-year battery life in always-on wearable health monitors and IoT endpoint nodes. |
| Input Offset Voltage | 20 µV (typ) - ensures <10 µV error in 0–100 mV biomedical transducer outputs without trimming. |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads to rail while maintaining linearity, suitable for driving ADC reference buffers or DAC output stages. |
| Shutdown Current | 16 nA - reduces system standby power by >1000× versus active mode, critical for duty-cycled sensing. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive sensors and industrial process controllers. |
Pinout & Package
TLV2450ID is packaged in a 6-pin SOT-23 (DBV) package with exposed pad for thermal performance. Pin 1 is marked by a molded dot or beveled edge; pin numbering follows standard counterclockwise orientation from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; high-impedance during shutdown. |
| 2 (IN−) | Inverting input | CMOS input with bias current <5 nA; accepts signals from 0 V to VDD. |
| 3 (IN+) | Non-inverting input | CMOS input with bias current <5 nA; supports true single-supply differential sensing. |
| 4 (GND) | Analog ground reference | Must be connected to clean system ground plane; shared return for input and output paths. |
| 5 (SHDN) | Shutdown control | Active-high logic: ≥2 V (at VDD = 5 V) or ≥0.5 V (at VDD = 3 V) enables operation; ≤0.8 V (5 V) or ≤0.5 V (3 V) disables. |
| 6 (VDD+) | Positive supply | Accepts 2.7–6 V; decoupling capacitor (0.1 µF) required within 5 mm of pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input/output | Enables full dynamic range utilization in 3 V systems - e.g., 0–3 V ADC input scaling without external level shifters. |
| Ultralow 23 µA supply current | Permits integration into energy-harvesting nodes where average current budget is <100 µA. |
| 16 nA shutdown current | Supports microsecond-scale wake-up latency while minimizing quiescent drain in sleep-mode telemetry. |
| 220 kHz GBW at 23 µA | Outperforms competing micropower op-amps (e.g., 100 kHz at same current), enabling faster settling in multiplexed sensor arrays. |
| Specified from −40°C to 125°C | Eliminates derating calculations for automotive cabin modules and industrial motor control feedback circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 17 µV max offset (−40°C to 125°C); 17 µA supply current; no shutdown pin. | Lacks integrated shutdown; better DC accuracy but higher cost and no low-power sleep mode. | Choose when long-term drift <0.02 µV/°C is mandatory and shutdown is implemented externally. |
| MCP6001T-I/OT | 20 µA supply current; 100 kHz GBW; rail-to-rail I/O; no shutdown; 1.8–6.0 V range. | Lower bandwidth limits use in fast-sampling sensor interfaces; wider VDD range suits 1.8 V MCU integration. | Choose for cost-sensitive consumer wearables where 100 kHz bandwidth suffices and shutdown is unnecessary. |
Compared with OPA333AIDBVR and MCP6001T-I/OT, TLV2450ID uniquely combines shutdown capability, 220 kHz bandwidth, and guaranteed −40°C to 125°C operation in a 6-pin SOT-23 - making it optimal for thermally demanding, battery-constrained industrial and medical applications requiring active power gating.

FAQ
What is the maximum operating temperature range for TLV2450ID?
The TLV2450ID is rated for operation from −40°C to 125°C, as confirmed by TI's SLOS218F datasheet Section "Recommended Operating Conditions". This full industrial temperature range is guaranteed across all electrical specifications including input offset voltage, supply current, and gain-bandwidth product - making TLV2450ID suitable for under-hood automotive and factory-floor applications where ambient temperatures exceed 85°C.
Does TLV2450ID support true rail-to-rail input common-mode range?
Yes, TLV2450ID supports rail-to-rail input common-mode voltage range from 0 V to VDD, verified in the "Electrical Characteristics" table (page 5) and Figure 1–2 of the SLOS218F datasheet. At VDD = 3 V, input offset voltage remains stable across 0–3 V common-mode range; at VDD = 5 V, it holds across 0–5 V - enabling direct interfacing with resistive sensors and single-supply ADC drivers without external bias networks.
What is the typical shutdown current of TLV2450ID and how is shutdown activated?
The typical shutdown current of TLV2450ID is 16 nA per channel, measured at 25°C with SHDN ≤ 0.5 V (VDD = 3 V) or ≤ 0.8 V (VDD = 5 V). Shutdown is activated by pulling the SHDN pin low; the output enters high-impedance state and supply current drops by >1000×. Turnoff time is 836 ns, and turnon time is 59 µs - documented in the "Operating Characteristics" table (page 6).
Can TLV2450ID drive a 10 kΩ load to rail at 3 V supply?
Yes, TLV2450ID can drive a 10 kΩ load to within 250 mV of each rail at 3 V supply while delivering ±2.5 mA, as stated in the "Description" section (page 1) and verified in Figure 11–13 of the SLOS218F datasheet. At 3 V, VOL = 0.16 V (max) and VOH = 2.83 V (min) with 500 µA load - confirming usable 2.67 V output swing, sufficient for driving 12-bit ADC references or comparator inputs in low-voltage systems.
Is TLV2450ID pin-compatible with other devices in the TLV245x family?
No, TLV2450ID is not pin-compatible with TLV2451ID or dual-channel variants. TLV2450ID uses a 6-pin SOT-23 (DBV) package with pins OUT, IN−, IN+, GND, SHDN, VDD+. TLV2451ID uses a 5-pin SOT-23 (no SHDN), and TLV2452/3 use MSOP packages with different pin counts and assignments - confirmed in the "TLV245x PACKAGE PINOUTS" diagram (page 3) of the SLOS218F datasheet.
