Product details
Overview
TLV2453IDGSR 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, 23 µA/channel supply current, ±10 mA output drive, 20 µV typical input offset voltage, 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 TLV2453IDGSR datasheet, TLV2453IDGSR pinout, TLV2453IDGSR application, or TLV2453IDGSR equivalent, key selection criteria include shutdown current (16 nA/ch), rail-to-rail swing under load, input offset stability over temperature, and MSOP-10 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2453IDGSR 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.
It features independent shutdown control per channel (pins 5 and 9), placing outputs in high-impedance state and reducing quiescent current to 16 nA per channel. Fully specified across −40°C to +125°C, it maintains 220 kHz GBW and 106 dB PSRR at 3 V and 5 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, two-cell alkaline, and regulated 3.3 V/5 V rails without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - enables stable amplification of DC–200 kHz signals (e.g., ECG, thermistor, strain gauge outputs) with minimal phase lag. |
| Supply Current (per channel) | 23 µA - allows >1-year battery life in always-on wearable sensors powered by CR2032 coin cells. |
| Input Offset Voltage (typ) | 20 µV - ensures <10 µV system-level error in 16-bit ADC front-ends with gain ≤100. |
| Output Drive Capability | ±10 mA - directly drives 500 Ω loads (e.g., ADC reference buffers, analog multiplexer inputs) without external boost stages. |
| Shutdown Current (per channel) | 16 nA - reduces total system standby power to sub-100 nA when both channels disabled, critical for energy-harvesting nodes. |
| PSRR | 106 dB - rejects ripple from noisy switching regulators, preserving signal integrity in mixed-signal embedded systems. |
Pinout & Package
TLV2453IDGSR is housed in a 10-pin MSOP (DGS) package with exposed thermal pad, measuring 3 mm × 3 mm × 1.05 mm - optimized for high-density portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Channel A output | Delivers rail-to-rail buffered signal; sinks/sources ±10 mA; high-impedance during SHDN_A assertion. |
| 2 (IN−A) | Channel A inverting input | CMOS input with 0.3–4.5 nA bias current; supports rail-to-rail common-mode range (0 V to VDD). |
| 3 (IN+A) | Channel A non-inverting input | Matches IN−A characteristics; enables precision instrumentation and difference amplification. |
| 4 (GND) | Analog ground reference | Common return for both channels; must be low-impedance and isolated from digital ground. |
| 5 (SHDN_A) | Channel A shutdown control | Active-low logic input; pulls to GND to disable Channel A (16 nA IQ); floats or ties to VDD to enable. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7–6 V; decoupling capacitor (0.1 µF) required within 2 mm for stability. |
| 7 (OUTB) | Channel B output | Independent rail-to-rail output; identical drive and shutdown behavior as OUTA. |
| 8 (IN−B) | Channel B inverting input | Electrically isolated from Channel A; enables dual-sensor simultaneous sampling. |
| 9 (SHDN_B) | Channel B shutdown control | Independent active-low control; allows asymmetric power management (e.g., keep Channel A active while sleeping Channel B). |
| 10 (IN+B) | Channel B non-inverting input | Full rail-to-rail common-mode support; matches IN+A performance for matched dual-channel designs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3 V systems - e.g., 0–3.3 V sensor output digitized by 12-bit SAR ADC without clipping. |
| Ultralow 23 µA/channel IQ | Reduces thermal drift and self-heating in sealed enclosures (e.g., implantable monitors), improving long-term measurement accuracy. |
| Independent dual shutdown | Permits dynamic channel gating in multi-sensor nodes - e.g., sleep pressure sensor channel while keeping temperature channel active. |
| 220 kHz GBW at 23 µA | Outperforms competing micropower op-amps (e.g., MCP6002) by >2× bandwidth per µA, enabling faster settling in data acquisition cycles. |
| Specified −40°C to +125°C | Validates operation in automotive cabin modules, industrial motor controllers, and outdoor IoT edge devices without derating. |

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 |
|---|---|---|---|
| MCP6022-E/SN | Higher supply current (100 µA/ch), lower GBW (1 MHz), no shutdown function, SOIC-8 package. | Lacks per-channel shutdown and ultralow IQ; suited for higher-speed, non-battery applications. | Select when bandwidth >1 MHz is required and shutdown is unnecessary; avoid for energy-constrained designs. |
| OPA2333AIDR | Zero-drift architecture, 17 µA/ch IQ, 350 kHz GBW, no shutdown, SOIC-8 package. | Superior VIO drift (0.02 µV/°C) but no shutdown; requires external enable circuitry for power gating. | Prefer for ultra-stable DC measurements (e.g., precision weigh scales); TLV2453IDGSR better for dynamic low-power sensing with integrated control. |
Compared with MCP6022-E/SN and OPA2333AIDR, the TLV2453IDGSR uniquely combines dual independent shutdown, 23 µA IQ, rail-to-rail I/O, and MSOP-10 packaging - making it the only option that meets simultaneous requirements for sub-100 nA standby, space-constrained layout, and 220 kHz signal fidelity in portable medical and industrial edge nodes.

FAQ
What is the operating temperature range for TLV2453IDGSR?
The TLV2453IDGSR is rated for operation from −40°C to +125°C (I-suffix grade), fully specified across this range for parameters including gain-bandwidth product, input offset voltage, and supply current - making it suitable for automotive, industrial, and outdoor medical applications where ambient extremes are expected.
Does TLV2453IDGSR support true rail-to-rail input and output?
Yes, TLV2453IDGSR supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swings within 250 mV of each rail while sourcing/sinking 2.5 mA). This capability is confirmed in the datasheet's Electrical Characteristics tables and Typical Characteristics curves (Figures 1–2, 11–14).
How does the shutdown feature work on TLV2453IDGSR?
TLV2453IDGSR has two independent active-low shutdown pins (SHDN_A on pin 5, SHDN_B on pin 9). Pulling either pin to GND disables its respective channel, placing the output in high-impedance state and reducing quiescent current to 16 nA per disabled channel - verified in the Electrical Characteristics table (IDD(SHDN)) and Figure 35–41.
What is the maximum capacitive load TLV2453IDGSR can drive stably?
TLV2453IDGSR maintains 56° phase margin with up to 1000 pF capacitive load (RL = 10 kΩ), as documented in the Operating Characteristics table and Figure 24. For loads >100 pF, a series resistor (10–50 Ω) between amplifier output and capacitance is recommended to ensure stability in production designs.
Is TLV2453IDGSR pin-compatible with other devices in the TLV245x family?
No - TLV2453IDGSR uses the 10-pin MSOP (DGS) package with dedicated SHDN pins, whereas TLV2452 uses 8-pin MSOP (DGK) without shutdown, and TLV2451 uses 5-pin SOT-23. Pin compatibility is limited to same-package variants (e.g., TLV2453IDGS and TLV2453AIDGS), not cross-package or cross-channel-count members.
