Product details
Overview
TLV2453IDR 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 - enabling high-precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2453IDR datasheet, TLV2453IDR pinout, TLV2453IDR application, or TLV2453IDR equivalent, key selection criteria include shutdown functionality (16 nA/ch), rail-to-rail swing under 2.5-mA load, input offset voltage (20 µV typ), PSRR (106 dB), and MSOP-10 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2453IDR integrates two independent amplifiers with dedicated shutdown control per channel (pins 5 and 10), supporting independent power gating in multi-stage analog signal chains. Its rail-to-rail input stage uses complementary differential pairs, while the output stage employs Class AB push-pull architecture to sustain ±10 mA into resistive loads while maintaining linearity near supply rails.
Designed for single-supply operation down to 2.7 V, the device achieves 220 kHz gain-bandwidth at 5 V with 0.11 V/µs slew rate and 56° phase margin into 1000 pF, ensuring stable unity-gain follower and closed-loop configurations without external compensation in typical sensor interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports direct connection to Li-ion (3.0–4.2 V) and 3.3 V/5 V system rails without regulation. |
| Supply Current (per channel) | 23 µA - enables >1-year battery life in continuous-sensing wearable devices using CR2032 cells. |
| Gain-Bandwidth Product | 220 kHz - sufficient for anti-aliasing filtering and DC-coupled amplification of ECG, temperature, and strain gauge signals. |
| Input Offset Voltage (typ) | 20 µV - reduces baseline drift in precision instrumentation amplifiers and 16-bit ADC driver stages. |
| Output Drive Capability | ±10 mA - drives 500-Ω loads directly, eliminating need for external buffer stages in transducer interfaces. |
| Power Supply Rejection Ratio | 106 dB - suppresses ripple and noise from switching regulators feeding mixed-signal PCBs. |
| Rail-to-Rail I/O | Swings within 250 mV of rails at 2.5 mA - maximizes dynamic range in 3.3 V systems, preserving >90% of full-scale ADC input range. |
Pinout & Package
TLV2453IDR is housed in a 10-pin MSOP (DGS) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm - optimized for high-density portable PCBs requiring thermal efficiency and minimal footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Delivers amplified signal; capable of sourcing/sinking ±10 mA while maintaining rail-to-rail swing. |
| 2 (IN− A) | Channel A inverting input | Differential node for feedback networks; supports rail-to-rail common-mode input range (0 V to VDD). |
| 3 (IN+ A) | Channel A non-inverting input | High-impedance sensor interface node; input bias current ≤5 nA minimizes loading on high-Z sources. |
| 4 (GND) | Analog ground reference | Common return path for both channels; must be star-connected to avoid ground bounce in dual-channel layouts. |
| 5 (SHDN A) | Channel A shutdown control | Active-high logic input; pulls amplifier into 16 nA sleep mode when driven ≥2 V (at VDD = 5 V) or ≥0.5 V (at VDD = 3 V). |
| 6 (VDD+) | Positive supply rail | Single-supply input; accepts 2.7–6 V; internal ESD protection rated to ±2 kV HBM. |
| 7 (OUT B) | Channel B output | Independent output with identical drive capability and rail-to-rail performance as OUT A. |
| 8 (IN− B) | Channel B inverting input | Matches IN− A electrical characteristics; enables matched dual-channel configurations like instrumentation amps. |
| 9 (IN+ B) | Channel B non-inverting input | Electrically identical to IN+ A; supports differential sensing with common-mode rejection up to 80 dB. |
| 10 (SHDN B) | Channel B shutdown control | Independent gating; allows staggered wake-up or selective channel disable in multi-sensor systems. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel 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 industrial range (vs. −40°C to 125°C for TLV2453IDR); no difference in shutdown behavior or package. | Suitable for commercial-grade consumer electronics; not qualified for automotive or extended-temperature industrial deployments. | Select TLV2453CDR only if ambient operating temperature remains strictly within 0°C–70°C and cost sensitivity outweighs long-term reliability requirements. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift vs. 0.3 µV/°C for TLV2453IDR); higher supply current (17 µA vs. 23 µA); lower GBW (350 kHz); no shutdown function. | Better for ultra-stable DC-coupled applications (e.g., precision weight scales); unsuitable where per-channel power gating is required. | Choose OPA2333AIDR when offset drift dominates error budget and shutdown is unnecessary; TLV2453IDR remains superior for battery life and thermal robustness. |
Compared with TLV2453CDR, TLV2453IDR provides guaranteed operation across −40°C to 125°C - essential for automotive cabin modules and outdoor industrial nodes - while matching all electrical parameters. Against OPA2333AIDR, TLV2453IDR trades zero-drift performance for integrated shutdown, lower cost, and wider temperature qualification, making it optimal for cost-sensitive, thermally demanding portable instrumentation.

FAQ
What is the operating temperature range for TLV2453IDR?
The TLV2453IDR is specified for operation from −40°C to +125°C, meeting extended industrial temperature requirements. This range is validated across all key parameters including input offset voltage, supply current, and gain-bandwidth product - making TLV2453IDR suitable for under-hood automotive sensors and outdoor industrial monitoring equipment where thermal stability is critical.
Does TLV2453IDR support true rail-to-rail input and output operation?
Yes, TLV2453IDR 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 confirmed in the datasheet's Electrical Characteristics tables at both 3 V and 5 V supplies, enabling full utilization of 3.3 V ADC input ranges without level-shifting circuitry in TLV2453IDR-based designs.
How does the shutdown feature work on TLV2453IDR?
TLV2453IDR provides independent shutdown control via pins 5 (SHDN A) and 10 (SHDN B). Driving either pin high (≥2 V at VDD = 5 V or ≥0.5 V at VDD = 3 V) places the corresponding amplifier channel into ultralow-power mode drawing just 16 nA/channel. The output enters high-impedance state, preserving signal integrity in multi-channel systems where only selected amplifiers remain active - a key feature of TLV2453IDR not found in standard dual op-amps.
What package type is used for TLV2453IDR?
TLV2453IDR is supplied in a 10-pin MSOP (DGS) package with an exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. This compact, surface-mount package supports automated assembly and provides superior thermal performance over SOIC alternatives - critical for dense portable PCBs where heat dissipation and board area are constrained in TLV2453IDR implementations.
Can TLV2453IDR drive capacitive loads without instability?
TLV2453IDR maintains stability with capacitive loads up to 1000 pF, as verified by 56° phase margin measurements in the datasheet (Figure 24). For loads exceeding 1000 pF, external series resistance (typically 10–100 Ω) at the output is recommended to preserve phase margin. This robustness enables direct driving of ADC input capacitors and long PCB traces in TLV2453IDR-based data acquisition circuits without added isolation components.
