Product details
Overview
TLV2453AIDR 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, and 23 µA/channel supply current across 2.7 V to 6 V operation - enabling high-precision signal conditioning in battery-powered patient monitoring and data acquisition circuits.
For engineers reviewing the TLV2453AIDR datasheet, TLV2453AIDR pinout, TLV2453AIDR application, or TLV2453AIDR equivalent, key selection criteria include shutdown-enabled power management (16 nA/channel), rail-to-rail swing at 3 V/5 V, and guaranteed −40°C to 125°C industrial temperature performance in MSOP-10 packaging.
Technical Context
The TLV2453AIDR 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 1 nF capacitive loads.
Shutdown functionality is implemented via two independent digital control inputs (1SHDN and 2SHDN), placing each amplifier's output in high-impedance state while reducing quiescent current to 16 nA per channel - critical for intermittent-sensing architectures in medical wearables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - operates from single-cell Li-ion (3.0 V nominal) or two alkaline cells (3.2 V fresh) without regulation. |
| Gain-Bandwidth Product | 220 kHz - supports stable DC-coupled amplification up to ~20 kHz with ≥60° phase margin at AV = 1. |
| Supply Current per Channel | 23 µA - enables >1-year battery life in 10 µA-average-power sensor nodes using duty-cycled operation. |
| Input Offset Voltage (max) | 1300 µV - ensures ≤0.13% full-scale error in 1 V reference-based 12-bit ADC front-ends. |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly, eliminating external buffers in ECG electrode amplifiers. |
| Shutdown Current per Channel | 16 nA - reduces system standby power by >99.9% versus active mode, critical for FDA-cleared sleep monitors. |
| Common-Mode Rejection Ratio | 76 dB (min) - rejects 94% of 50/60 Hz interference in unshielded biomedical leads. |
Pinout & Package
TLV2453AIDR is housed in a 10-pin MSOP (DGS) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm - suitable for space-constrained wearable PCBs. Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Delivers rail-to-rail voltage with ±10 mA sourcing/sinking capability; high-Z during 1SHDN assertion. |
| 1IN− | Channel 1 inverting input | CMOS input with 0.3–4.5 nA bias current; accepts signals from 0 V to VDD. |
| 1IN+ | Channel 1 non-inverting input | CMOS input matching 1IN−; enables precision instrumentation amplifier configurations. |
| GND | Analog ground reference | Single-point return for all analog signals; must be isolated from digital ground in mixed-signal layouts. |
| 1SHDN | Channel 1 shutdown control | Active-high logic input; pulls output high-Z and cuts IDD to 16 nA when driven ≥0.8 V (at VDD = 5 V). |
| VDD+ | Positive supply rail | Accepts 2.7–6 V; decoupling capacitor (100 nF) required within 2 mm of this pin. |
| 2OUT | Channel 2 output | Independent rail-to-rail output; high-Z during 2SHDN assertion - enables dual-path signal processing. |
| 2IN− | Channel 2 inverting input | Electrically identical to 1IN−; supports differential pair or dual-filter topologies. |
| 2IN+ | Channel 2 non-inverting input | Matches 2IN− characteristics; allows synchronous sampling of two sensor channels. |
| 2SHDN | Channel 2 shutdown control | Independent enable/disable control; permits staggered wake-up of dual sensor paths to minimize peak current. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3 V systems - e.g., 0–3 V ECG waveform digitization without level-shifting. |
| Ultralow 23 µA/channel supply current | Reduces average power in 1 Hz-sampled temperature sensors to <1 µW - extending coin-cell life beyond 5 years. |
| Independent dual shutdown pins (1SHDN/2SHDN) | Allows per-channel power gating - essential for time-multiplexed biosensor arrays with sequential excitation. |
| Guaranteed operation from −40°C to 125°C | Validates performance in automotive cabin monitors or industrial process controllers without derating. |
| 220 kHz GBW with 0.11 V/µs slew rate | Supports accurate amplification of pulse oximeter IR/red LED drive signals up to 100 Hz with <0.5% distortion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2453CDR | Same electrical specs but rated for 0°C to 70°C; lacks extended temperature validation. | Suitable for commercial-grade consumer wearables, not certified medical or automotive use. | Select TLV2453CDR only if ambient operating temperature stays within 0–70°C and regulatory certification is not required. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift); higher 350 kHz GBW but 17 µA higher IDD (40 µA/channel). | Better for DC-critical applications like precision weight scales; less optimal for multi-year battery life. | Choose OPA2333AIDR when offset drift <0.5 µV over temperature is mandatory, accepting 74% higher quiescent current. |
Compared with TLV2453CDR, TLV2453AIDR provides validated −40°C to 125°C operation essential for field-deployed medical devices, while OPA2333AIDR trades ultralow power for near-zero drift - making TLV2453AIDR the optimal balance for long-life, wide-temperature, moderate-precision biosensing.

FAQ
What is the maximum operating temperature range for TLV2453AIDR?
The TLV2453AIDR is fully specified from −40°C to +125°C, with electrical parameters guaranteed across this extended industrial temperature range. This makes TLV2453AIDR suitable for under-hood automotive sensors, industrial control cabinets, and clinical-grade wearable devices where ambient temperatures exceed standard commercial limits.
Does TLV2453AIDR support true rail-to-rail input and output operation?
Yes, TLV2453AIDR supports rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 250 mV of each rail at 2.5 mA load). This capability is verified at both 3 V and 5 V supply voltages, enabling full-scale signal utilization in low-voltage systems without external level-shifting circuitry.
How does the shutdown feature work on TLV2453AIDR?
TLV2453AIDR features two independent shutdown pins (1SHDN and 2SHDN), each controlling one amplifier channel. When a shutdown pin is driven high (≥0.8 V at VDD = 5 V), its corresponding output enters high-impedance state and supply current drops to 16 nA per channel. Both channels remain fully functional when shutdown pins are low or floating (internal pull-down ensures default active state).
What package type is used for TLV2453AIDR?
TLV2453AIDR is packaged in a 10-pin MSOP (DGS) with an exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. This compact, surface-mount package supports high-density layouts in space-constrained applications such as disposable ECG patches and miniature IoT sensor nodes.
Can TLV2453AIDR drive capacitive loads without instability?
TLV2453AIDR maintains stability with capacitive loads up to 1 nF when properly compensated - demonstrated by 56° phase margin at CL = 1000 pF and RL = 10 kΩ. For loads >100 pF, a series resistor (10–50 Ω) between amplifier output and capacitance is recommended to preserve step response fidelity and prevent peaking.
