Product details
Overview
TLV2453IN from Texas Instruments is a dual-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/channel supply current, and operates from 2.7 V to 6 V. Its shutdown mode reduces current to 16 nA/channel, making it ideal for battery-powered patient monitoring and data acquisition circuits.
For engineers reviewing the TLV2453IN datasheet, TLV2453IN pinout, TLV2453IN application, or TLV2453IN equivalent, key selection considerations include its 10-pin PDIP package with integrated shutdown control per channel, rail-to-rail swing under 2.5-mA load, and guaranteed −40°C to 125°C operation across industrial and automotive temperature grades.
Technical Context
The TLV2453IN implements a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing within 250 mV of each rail at 2.5 mA load. Its internal architecture supports independent channel shutdown via dedicated SHDN pins, placing outputs in high-impedance state while maintaining 16 nA/channel quiescent current.
It is fully specified at both 3 V and 5 V single-supply operation, with PSRR of 106 dB and CMRR of 80 dB (typ) at 25°C. The device achieves stable unity-gain operation with 56° phase margin into 1000 pF capacitive loads, supporting direct driving of ADC inputs and sensor signal conditioning without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct integration into 3.3 V and 5 V systems without level-shifting |
| Gain-Bandwidth Product | 220 kHz - sufficient for DC-coupled sensor amplification and low-frequency filtering up to ~20 kHz |
| Supply Current per Channel | 23 µA - allows continuous operation for years on coin-cell batteries in always-on monitoring nodes |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads to rails and interfaces directly with SAR ADC reference buffers |
| Input Offset Voltage | 20 µV (typ) - supports precision DC measurements with <1 LSB error in 16-bit systems at 5 V full-scale |
| Shutdown Current per Channel | 16 nA - reduces total system standby power to sub-100 nA when both channels disabled |
| Operating Temperature Range | −40°C to 125°C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
TLV2453IN is housed in a 14-pin plastic DIP (PDIP-N) package with 0.3-inch body width and through-hole mounting. Pin 1 is identified by a beveled edge or molded dot; pin numbering follows standard counter-clockwise orientation from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel A output - rail-to-rail capable, sinks/sources ±10 mA, high-impedance in shutdown |
| 2 | 1IN− | Inverting input for Channel A - CMOS input with 0.3 nA bias current, supports 0 V to VDD common-mode range |
| 3 | 1IN+ | Non-inverting input for Channel A - identical electrical characteristics to 1IN− |
| 4 | GND | Analog ground reference - must be connected to system AGND plane with low-impedance path |
| 5 | 2IN+ | Non-inverting input for Channel B - electrically isolated from Channel A; shares no internal nodes |
| 6 | 2IN− | Inverting input for Channel B - independent biasing and offset, matched to Channel A within 300 µV max |
| 7 | 2OUT | Channel B output - functionally identical to 1OUT with separate load-driving capability |
| 8 | VDD+ | Positive supply - accepts 2.7–6 V; decoupling capacitor (0.1 µF) required within 1 cm |
| 9 | 1/2SHDN | Shared shutdown control - logic-low disables both amplifiers simultaneously; high-impedance when floating |
| 10 | NC | No internal connection - left unconnected; not bonded or tied internally |
| 11–14 | NC | No internal connection - unused pins; must remain unconnected per datasheet guidance |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V systems - measures signals from 0 V to 3.3 V and drives ADCs without clipping |
| Ultralow 23 µA/channel supply current | Reduces thermal load in sealed enclosures and extends battery life in wearable medical sensors beyond 5 years |
| Dual independent shutdown control | Allows selective channel disablement - e.g., keep Channel A active for wake-up detection while powering down Channel B |
| Guaranteed operation at 2.7 V | Supports brown-out resilience in Li-ion battery systems discharging from 4.2 V down to 2.7 V without performance degradation |
| 106 dB PSRR | Rejects switching noise from DC-DC converters - maintains <10 µV ripple on output when powered from noisy 3.3 V buck regulator |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2453IDR | Same silicon, 10-pin MSOP package with 0.5 mm pitch - 3.0 × 3.0 mm footprint vs. TLV2453IN's 19.1 × 6.6 mm DIP | Targeted at space-constrained PCBs; requires reflow soldering and microscope inspection | Select TLV2453IDR for high-density layouts where manual assembly or through-hole prototyping is not required |
| OPA2333AIDR | Zero-drift architecture; 0.1 µV/°C offset drift vs. TLV2453IN's 0.3 µV/°C; 17 µA/channel vs. 23 µA | Better for DC-critical applications like precision weight scales; higher cost and no shutdown function | Choose OPA2333AIDR only when sub-1 µV total offset error over temperature is mandatory - otherwise TLV2453IN offers superior power/performance balance |
Compared with TLV2453IDR, TLV2453IN provides mechanical robustness and hand-solderability at the expense of board area; versus OPA2333AIDR, it trades zero-drift precision for integrated shutdown and lower unit cost in volume production.

FAQ
What is the maximum operating temperature for TLV2453IN?
The TLV2453IN is rated for operation from −40°C to +125°C, meeting industrial and extended-temperature automotive requirements. This specification is guaranteed across all electrical parameters in the datasheet, including input offset voltage, PSRR, and output drive capability, with no derating required up to the maximum junction temperature of 150°C.
Does TLV2453IN support true rail-to-rail input and output operation?
Yes, TLV2453IN supports 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 achieved via complementary CMOS input stages and push-pull output topology, enabling full utilization of 3.3 V or 5 V supply rails in single-supply configurations.
How does the shutdown feature work on TLV2453IN?
The TLV2453IN uses a shared shutdown pin (Pin 9, labeled 1/2SHDN) that places both amplifier outputs in high-impedance state and reduces total supply current to 16 nA per channel. A logic-low input (≤0.5 V at VDD = 3 V or ≤0.8 V at VDD = 5 V) activates shutdown; the device resumes normal operation within 59 µs after shutdown deactivation.
What package type is TLV2453IN supplied in?
TLV2453IN is supplied in a 14-pin plastic DIP (PDIP-N) package with 0.3-inch body width and through-hole leads. It is distinct from surface-mount variants like TLV2453IDR (MSOP-10) and TLV2453CDGK (MSOP-8), and is intended for prototyping, manual assembly, and legacy through-hole manufacturing processes.
Can TLV2453IN drive capacitive loads directly?
TLV2453IN is stable with capacitive loads up to 1000 pF when configured as a unity-gain follower, as verified by 56° phase margin in the datasheet. For loads exceeding 1000 pF or in closed-loop gains <1, an external isolation resistor (e.g., 10 Ω–100 Ω) between output and capacitance is recommended to maintain stability and prevent peaking.
