Product details
Overview
TLV2452ID from Texas Instruments is a dual 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 precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2452ID datasheet, TLV2452ID pinout, TLV2452ID application, or TLV2452ID equivalent, key selection criteria include its rail-to-rail I/O swing at 3 V, shutdown current of 16 nA/channel, −40°C to 125°C industrial temperature range, and MSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2452ID employs a CMOS input stage enabling rail-to-rail common-mode input voltage range (0 V to VDD) and rail-to-rail output swing within 250 mV of each rail under 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 8), placing outputs in high-impedance state while reducing supply current to 16 nA/channel. No internal shutdown logic ties channels together - each amplifier shuts down independently when its SHDN pin is driven low.
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–20 kHz biosignals (ECG, pulse oximetry) with minimal phase lag. |
| Supply Current per Channel | 23 µA - allows continuous operation for >1 year on a 200 mAh coin cell in always-on sensor nodes. |
| Rail-to-Rail I/O | Input common-mode range 0 V to VDD; output swing within 250 mV of rails at 2.5 mA - maximizes dynamic range in 3 V systems. |
| Shutdown Current | 16 nA/channel - reduces total system standby power to sub-µW levels when amplifiers are inactive. |
| Input Offset Voltage | 20 µV (typ) - ensures <10 µV error contribution in 16-bit ADC front-ends with gain ≤100. |
| Output Drive | ±10 mA - drives 10 kΩ loads directly and interfaces with SAR ADC reference buffers without external gain stages. |
Pinout & Package
TLV2452ID is housed in an 8-pin MSOP (DGK) package - 3.0 mm × 3.0 mm footprint, 0.65 mm pitch, exposed thermal pad optional. Designed for reflow-compatible assembly and high-density routing in portable instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail buffered signal; sinks/sources ±10 mA; high-impedance during A-channel shutdown. |
| 2 (IN− A) | Inverting input A | CMOS input with 0.3 nA bias current; accepts 0 V to VDD common-mode voltage. |
| 3 (IN+ A) | Non-inverting input A | CMOS input matched to IN− A; enables precision differential sensing with low offset drift. |
| 4 (GND) | Analog ground reference | Single ground connection for both amplifiers; requires low-impedance local decoupling. |
| 5 (SHDN A) | Channel A shutdown control | Active-low logic input; pulls below 0.5 V (at 3 V VDD) to disable A amplifier and reduce IDD to 16 nA. |
| 6 (VDD+) | Positive supply rail | Accepts 2.7–6 V; supplies both amplifiers and shutdown logic; bypass with 100 nF ceramic capacitor. |
| 7 (OUT B) | Amplifier B output | Independent output identical to OUT A; no crosstalk coupling - 90 dB typical isolation at 1 kHz. |
| 8 (SHDN B) | Channel B shutdown control | Active-low logic input; fully independent of SHDN A - enables asymmetric power gating per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow quiescent current | 23 µA/channel enables multi-year battery life in wearable ECG monitors and glucose meters. |
| Rail-to-rail input and output | Full 0–3 V input range and 0.1–2.9 V output swing at 3 V supply maximize SNR in low-voltage ADC interfaces. |
| Independent dual-channel shutdown | Separate SHDN pins allow selective disabling - e.g., keep A active for sensor biasing while shutting down B during idle cycles. |
| High PSRR (106 dB) | Rejects ripple from switching regulators, maintaining accuracy in mixed-signal systems with shared 3.3 V LDO + DC/DC supplies. |
| Stable into capacitive loads | 56° phase margin into 1000 pF supports direct driving of long traces or ADC input capacitance without external compensation. |

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 |
|---|---|---|---|
| TLV2452CD | Same electrical specs but rated for 0°C to 70°C only; no shutdown functionality; SOT-23-8 package. | Not suitable for industrial environments requiring −40°C to 125°C operation or power-gating capability. | Select TLV2452CD only for cost-sensitive commercial-grade applications with ambient temperature control. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift); higher 350 kHz GBW; 17 µA/channel; no shutdown; SOIC-8 package. | Better DC precision but lacks independent shutdown and rail-to-rail output swing at light loads. | Choose OPA2333AIDR when ultra-low offset drift dominates over power gating and output swing requirements. |
Compared with TLV2452CD, TLV2452ID adds industrial temperature range and per-channel shutdown - critical for field-deployed equipment. Versus OPA2333AIDR, TLV2452ID trades zero-drift performance for lower system-level power management complexity and guaranteed rail-to-rail output drive.

FAQ
What is the operating temperature range for TLV2452ID?
The TLV2452ID is specified for operation from −40°C to +125°C, meeting industrial and extended-temperature requirements. This rating is confirmed in the "Recommended Operating Conditions" table of the official TI datasheet SLOS218F, where the "I suffix" explicitly denotes the −40°C to 125°C range. The device maintains full electrical performance across this span, including 23 µA/channel supply current and 220 kHz gain-bandwidth product.
Does TLV2452ID support true rail-to-rail output swing?
Yes, TLV2452ID provides true rail-to-rail output swing: it drives within 250 mV of both supply rails (VDD and GND) while sourcing or sinking 2.5 mA, as verified in the "Electrical Characteristics" section of the TI datasheet SLOS218F. At 3 V supply, this yields a usable output range of 0.1 V to 2.9 V - essential for maximizing dynamic range in low-voltage data acquisition systems using TLV2452ID.
How does the shutdown feature work on TLV2452ID?
TLV2452ID implements independent active-low shutdown per channel: pin 5 (SHDN A) controls amplifier A, and pin 8 (SHDN B) controls amplifier B. When either pin is pulled below 0.5 V (at 3 V VDD), that amplifier's output enters high-impedance state and its supply current drops to 16 nA/channel. Both channels remain fully functional when their respective SHDN pins are held ≥2 V - confirmed in the "Electrical Characteristics" table under IDD(SHDN).
What package type is used for TLV2452ID?
TLV2452ID is packaged in an 8-pin MSOP (Micro Small Outline Package), designated DGK in TI's ordering nomenclature. This package measures 3.0 mm × 3.0 mm with 0.65 mm lead pitch and is RoHS-compliant. The "DGK" suffix appears in TI's official "Available Options" table for TLV2452ID, confirming its exclusive use for this temperature-grade variant - distinct from SOIC-8 (D) or PDIP-8 (P) variants.
Can TLV2452ID drive capacitive loads without oscillation?
Yes, TLV2452ID remains stable into capacitive loads up to 1000 pF, with a measured phase margin of 56° at 3 V supply - documented in Figure 24 ("Phase Margin vs Load Capacitance") of the TI datasheet SLOS218F. This allows direct interfacing with ADC input capacitance (typically 10–30 pF), long PCB traces, or RC anti-aliasing filters without external compensation networks when using TLV2452ID.
