Product details
Overview
TLV2453CDGS from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier in a 10-pin MSOP package, delivering 23 µA/channel supply current, 220 kHz gain-bandwidth product, ±10 mA output drive, and 20 µV typical input offset voltage across 2.7 V to 6 V supply range - enabling precision signal conditioning in ultra-low-power portable medical sensors and battery-powered data acquisition systems.
For engineers reviewing the TLV2453CDGS datasheet, TLV2453CDGS pinout, TLV2453CDGS application, or TLV2453CDGS equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, application-specific implementation value, and two confirmed alternative options with documented functional and packaging differences.
Technical Context
The TLV2453CDGS integrates two independent op-amps with shutdown control per channel (pins 5 and 10), supporting independent enable/disable for power-gating in multi-stage analog signal chains. Its 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) maximize dynamic range in single-supply 3 V systems.
It features ultralow quiescent current (23 µA/ch active, 16 nA/ch in shutdown), high PSRR (106 dB), and stable unity-gain operation with 56° phase margin into 1 nF capacitive loads - making it suitable for driving ADC inputs, sensor front-ends, and low-noise instrumentation amplifiers without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact dual-path signal processing or differential pair configuration in one package. |
| Supply Voltage Range | 2.7 V to 6 V - supports direct operation from single Li-ion, 3.3 V logic rails, or dual ±1.35 V supplies. |
| Gain-Bandwidth Product | 220 kHz - sufficient for DC-coupled sensor amplification, low-frequency filtering, and 12-bit ADC driver applications up to ~10 kHz. |
| Input Offset Voltage (typ) | 20 µV - ensures <1 LSB error in 12-bit systems with 2.5 V reference when used in unity-gain buffer or non-inverting amplifier. |
| Output Drive | ±10 mA - drives 250 Ω loads directly, eliminating need for external buffers in DAC output stages or LED bias circuits. |
| Shutdown Current | 16 nA per channel - reduces system standby power by >99.9% versus active mode, critical for battery life in intermittent-sampling devices. |
| PSRR | 106 dB - rejects ripple on shared 3.3 V rails, maintaining accuracy in mixed-signal PCBs with digital switching noise. |
Pinout & Package
TLV2453CDGS uses a 10-pin MSOP (DGS) package with exposed thermal pad (not electrically connected). Pin 1 is marked by a molded dot or beveled edge; pin numbering follows standard MSOP convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives loads up to ±10 mA. |
| 2 | IN− A | Inverting input for Channel A - high-impedance node (10⁹ Ω) for precision feedback networks. |
| 3 | IN+ A | Non-inverting input for Channel A - accepts signals from 0 V to VDD with minimal error. |
| 4 | GND | Analog ground reference - must be low-impedance connection to minimize noise coupling between channels. |
| 5 | SHDN A | Channel A shutdown control - logic-high (>2 V at VDD = 5 V) enables amplifier; logic-low disables with high-Z output. |
| 6 | VDD+ | Positive supply - decoupling capacitor (0.1 µF) required within 5 mm for stability. |
| 7 | OUT B | Amplifier B output - independently controllable; no crosstalk impact on Channel A when disabled. |
| 8 | IN− B | Inverting input for Channel B - matched offset and bias performance to Channel A. |
| 9 | IN+ B | Non-inverting input for Channel B - supports true differential input configurations with matched layout. |
| 10 | SHDN B | Channel B shutdown control - identical threshold and timing behavior as SHDN A. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full-scale signal utilization in 3 V systems - e.g., 0–3 V sensor outputs digitized directly by 3 V ADCs without level-shifting. |
| Ultralow 23 µA/channel supply current | Extends battery life in wearable ECG monitors: 10 µA average current allows >1-year operation on CR2032 coin cell (220 mAh) with 1% duty cycle. |
| Independent per-channel shutdown | Permits dynamic power management - e.g., disable Channel B during sleep while keeping Channel A active for wake-up detection. |
| 106 dB PSRR | Maintains 12-bit linearity in noisy environments - suppresses 10 mV ripple on 3.3 V rail to <100 nV at output. |
| 20 µV typical input offset | Reduces calibration overhead in factory-trimmed medical sensors - eliminates need for external offset nulling circuitry. |
| Stable with 1 nF capacitive load | Drives long traces or ADC input capacitance directly - avoids instability issues common in micropower op-amps. |

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 |
|---|---|---|---|
| TLV2453IDGS | Same electrical specs and pinout, but rated for −40°C to 125°C industrial temperature range vs. TLV2453CDGS (0°C to 70°C). | Required for automotive cabin sensors or industrial process controllers operating outside commercial temperature limits. | Select TLV2453IDGS when ambient operating temperature exceeds 70°C or requires extended reliability validation. |
| OPA2333AIDGSR | Zero-drift architecture (0.02 µV/°C drift), lower 1/f noise, but higher 17 µA supply current and no shutdown function. | Better for DC-critical applications like precision weigh scales; unsuitable where per-channel power gating is needed. | Choose OPA2333AIDGSR only if sub-µV offset drift dominates over shutdown capability and quiescent current budget. |
Compared with TLV2453CDGS, TLV2453IDGS offers identical functionality with extended temperature rating, while OPA2333AIDGSR trades shutdown and ultra-low power for zero-drift performance - making TLV2453CDGS optimal for cost-sensitive, battery-constrained, temperature-stable portable instrumentation.

FAQ
What is the operating temperature range for TLV2453CDGS?
The TLV2453CDGS is specified for operation from 0°C to 70°C (commercial temperature grade). This range is validated per TI's SLOS218F datasheet and applies to all electrical parameters including input offset voltage, gain-bandwidth, and shutdown current. For extended temperature applications, consider TLV2453IDGS (−40°C to 125°C).
Does TLV2453CDGS support true rail-to-rail input and output?
Yes, TLV2453CDGS supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swings within 250 mV of both rails under 2.5 mA load). This is confirmed in the device description and electrical characteristics tables of the official datasheet, enabling full dynamic range utilization in 3 V systems.
How does the shutdown feature work on TLV2453CDGS?
TLV2453CDGS has independent shutdown controls on pins 5 (SHDN A) and 10 (SHDN B). Driving either pin below 0.5 V (at VDD = 3 V) or 0.8 V (at VDD = 5 V) disables the corresponding amplifier channel, reducing its supply current to 16 nA and placing the output in high-impedance state. Both channels remain fully functional when pins are pulled high.
What is the typical input offset voltage of TLV2453CDGS?
The typical input offset voltage of TLV2453CDGS is 20 µV at 25°C and VDD = 3 V or 5 V, as specified in the "Electrical Characteristics" section of the TI datasheet SLOS218F. Maximum offset is 1300 µV over the full commercial temperature range (0°C to 70°C), ensuring predictable DC accuracy in precision sensor interfaces.
Can TLV2453CDGS drive capacitive loads without oscillation?
Yes, TLV2453CDGS is stable with up to 1 nF capacitive load, as verified by phase margin measurements (56° at CL = 1000 pF, RL = 10 kΩ) in the datasheet's "Operating Characteristics" section. This allows direct connection to ADC inputs, long PCB traces, or RC filters without external isolation resistors or compensation networks.
