Product details
Overview
TLV2454AIDR from Texas Instruments is a quad 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. It is used in patient monitoring front-ends where rail-to-rail swing maximizes dynamic range at 3 V supply.
For engineers reviewing the TLV2454AIDR datasheet, TLV2454AIDR pinout, TLV2454AIDR application, or TLV2454AIDR equivalent, key selection criteria include shutdown capability absence (TLV2454 has no SHDN pin), TSSOP-14 package thermal performance, and guaranteed −40°C to 125°C operation with 1000 µV max input offset voltage.
Technical Context
The TLV2454AIDR implements a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing within 250 mV of rails under 2.5 mA load. Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate support precision DC-coupled signal conditioning in battery-powered data acquisition.
It features 106 dB power supply rejection ratio and 80 dB common-mode rejection ratio at 25°C, with input bias current below 5 nA and input offset voltage specified at 300–1000 µV (typ/max) across −40°C to 125°C. No internal shutdown control is present-this distinguishes it from TLV2450/3/5 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion and dual-cell alkaline systems without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - enables stable unity-gain buffering and low-frequency filtering up to ~20 kHz with margin. |
| Supply Current per Channel | 23 µA - allows four op-amps to operate continuously on <100 µA total, critical for multi-sensor wearables. |
| Input Offset Voltage (max) | 1000 µV - ensures ≤1 mV error in 1× gain sensor interfaces at room temperature. |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly, eliminating external buffers in analog front-ends. |
| Rail-to-Rail I/O | Yes - full 0 V to VDD input range and output swing to within 250 mV of rails preserves signal headroom in 3 V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2454CDR | Same quad RRIO architecture but rated for 0°C to 70°C only; 1300 µV max input offset voltage vs. 1000 µV for TLV2454AIDR. | Suitable for commercial-grade portable electronics but not automotive or extended-temperature industrial use. | Select TLV2454CDR only if ambient operating temperature remains within 0–70°C and higher offset is acceptable. |
| OPA2333PWR | Zero-drift architecture; 0.02 µV/°C offset drift vs. 0.3 µV/°C for TLV2454AIDR; 17 µA/channel supply current; no rail-to-rail output. | Better DC precision for long-term sensor drift compensation, but limited output swing reduces dynamic range in 3 V systems. | Choose OPA2333PWR when microvolt-level DC stability outweighs rail-to-rail output requirement and power is secondary. |
Compared with TLV2454CDR, TLV2454AIDR provides guaranteed −40°C to 125°C operation and tighter input offset spec, making it suitable for automotive and industrial deployments; versus OPA2333PWR, TLV2454AIDR trades zero-drift precision for rail-to-rail output and lower cost, prioritizing signal headroom over ultra-low drift.

FAQ
What is the maximum input offset voltage specification for TLV2454AIDR over its full operating temperature range?
The TLV2454AIDR has a maximum input offset voltage of 1300 µV across the full −40°C to 125°C operating range, with a typical value of 300 µV at 25°C. This specification is verified per the SLOS218F datasheet Section 5, Electrical Characteristics, and applies to all four channels under VDD = 3 V or 5 V conditions.
Does TLV2454AIDR include a shutdown pin, and how does it differ from other TLV245x variants?
No, TLV2454AIDR does not include a shutdown pin. Unlike TLV2450, TLV2453, and TLV2455 which integrate SHDN terminals, the TLV2454 variant is a fixed-function quad op-amp with no power-down capability. This simplifies layout and eliminates control logic but precludes dynamic current reduction during idle periods.
What package type and dimensions does TLV2454AIDR use, and is it RoHS compliant?
TLV2454AIDR uses the TSSOP-14 package (4.4 mm × 5.0 mm body, 1.2 mm height) with lead pitch of 0.65 mm. It is RoHS compliant and meets JEDEC standard J-STD-020 moisture sensitivity level 1, supporting standard Pb-free reflow profiles without preconditioning.
Can TLV2454AIDR drive capacitive loads, and what is its phase margin with 1000 pF?
Yes, TLV2454AIDR is stable with capacitive loads up to 1000 pF, maintaining a phase margin of 56° and gain margin of 7 dB when driving 10 kΩ || 1000 pF (per Figure 24 and Section 8 of SLOS218F). For loads >100 pF, series output resistance (10–50 Ω) is recommended to ensure robust step response.
What is the output voltage swing capability of TLV2454AIDR at 3 V supply and 2.5 mA load?
At VDD = 3 V and 2.5 mA load, TLV2454AIDR delivers rail-to-rail output swing to within 250 mV of each supply rail - i.e., minimum VOL ≈ 0.15 V and maximum VOH ≈ 2.85 V (per datasheet Section 5, Electrical Characteristics, Table 1). This enables full 0–3 V signal utilization in single-supply sensor interfaces.
