Product details
Overview
TLV2450IDR 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, 23 µA supply current per channel, ±10 mA output drive, 20 µV typical input offset voltage, and operates from 2.7 V to 6 V - enabling high-precision signal conditioning in battery-powered medical sensors and patient monitoring front-ends.
For engineers reviewing the TLV2450IDR datasheet, TLV2450IDR pinout, TLV2450IDR application, or TLV2450IDR equivalent, key selection criteria include shutdown current (16 nA/channel), rail-to-rail swing under load, 125°C industrial temperature rating, SOT-23-6 packaging density, and verified performance at 3 V supply - critical for space-constrained, long-life portable instrumentation designs.
Technical Context
The TLV2450IDR 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 56° phase margin into 1000 pF capacitive loads and achieves 220 kHz gain-bandwidth product at 5 V while consuming only 23 µA per channel.
Shutdown functionality is implemented via a dedicated SHDN pin that places the output in high-impedance state and reduces quiescent current to 16 nA/channel. The device is fully specified across −40°C to +125°C and validated for single-supply operation down to 2.7 V, making it suitable for wide-input-range industrial sensor interfaces requiring low-noise, low-drift amplification without external level-shifting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2450CDR | Same electrical specs but rated for 0°C to 70°C; lacks extended temperature qualification | Suitable for commercial-grade consumer wearables, not industrial or automotive deployments | Select TLV2450CDR only if ambient operating temperature stays below 70°C and cost sensitivity outweighs reliability requirements |
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C drift vs. TLV2450IDR's 0.3 µV/°C; higher 35 µA supply current | Better long-term DC stability in unattended temperature loggers; trades 52% higher current for 3× lower drift | Choose OPA333AIDBVR when drift-induced error dominates over battery life; TLV2450IDR preferred for fixed-calibration, low-power use cases |
Compared with TLV2450CDR, TLV2450IDR provides guaranteed operation to +125°C and superior thermal stability for industrial field equipment; versus OPA333AIDBVR, TLV2450IDR offers 34% lower supply current and simpler biasing at the cost of higher input offset drift - making it optimal for cost-sensitive, battery-limited applications where factory calibration suffices.

FAQ
What is the operating temperature range for TLV2450IDR?
The TLV2450IDR is rated for operation from −40°C to +125°C, meeting industrial-grade requirements. This specification is confirmed in the "Recommended Operating Conditions" table of the official TI datasheet (SLOS218F), where the "I-suffix" designation explicitly defines this extended temperature range. All electrical parameters - including supply current, offset voltage, and gain-bandwidth - are guaranteed across this full range, making TLV2450IDR suitable for harsh-environment applications like motor control feedback or outdoor sensor nodes.
Does TLV2450IDR support true rail-to-rail input and output operation?
Yes, TLV2450IDR 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 explicitly stated in the device description and verified in the "Electrical Characteristics" tables, where VOH and VOL values are measured at VDD = 3 V and 5 V with loads up to ±10 mA. The architecture enables full-scale signal utilization in 3 V systems - critical for maximizing ADC resolution without external level-shifting circuitry in TLV2450IDR-based designs.
What is the shutdown current consumption of TLV2450IDR?
The TLV2450IDR draws 16 nA per channel in shutdown mode, as specified in the "Electrical Characteristics" table under parameter IDD(SHDN) for TLV245xC and TLV245xI variants. This value is measured at 25°C with SHDN pin driven low (SHDN = −VDD or GND depending on configuration), and the output enters high-impedance state. At full temperature range (−40°C to +125°C), maximum shutdown current remains ≤70 nA - enabling multi-year battery operation in intermittently active TLV2450IDR sensor nodes.
Is TLV2450IDR pin-compatible with other members of the TLV245x family?
No, TLV2450IDR is not pin-compatible with dual or quad variants (e.g., TLV2452, TLV2454) due to differing channel counts and pin assignments. However, among single-channel variants, TLV2450IDR (6-pin SOT-23) shares identical pinout with TLV2451IDR (5-pin SOT-23) except for the NC pin - but TLV2451 lacks shutdown functionality. The TLV2450IDR pinout (OUT, IN−, IN+, GND, SHDN, VDD+) is unique to the shutdown-enabled single-channel SOT-23 variant and must be laid out accordingly in TLV2450IDR PCB designs.
What load capacitance can TLV2450IDR safely drive without instability?
TLV2450IDR maintains stability with up to 1000 pF capacitive load at unity gain, as confirmed by the Phase Margin vs. Load Capacitance plot (Figure 24) and the "Operating Characteristics" table specifying 56° phase margin at CL = 1000 pF. This capability allows direct connection to typical 10–100 pF ADC input capacitances or longer PCB traces without external isolation resistors - a key advantage over many micropower op-amps that require ≥100 Ω series resistance for stability. For loads exceeding 1000 pF, external compensation is recommended in TLV2450IDR applications.
