Product details
Overview
TLV2454CD 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, 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 TLV2454CD datasheet, TLV2454CD pinout, TLV2454CD application, or TLV2454CD equivalent, key selection criteria include its rail-to-rail I/O swing at micropower consumption, shutdown capability (not present in this variant), TSSOP-14 package footprint, and guaranteed performance across 0°C to 70°C industrial temperature range.
Technical Context
The TLV2454CD 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 220 kHz gain-bandwidth product and 0.11 V/µs slew rate support stable unity-gain buffering and low-frequency amplification without phase reversal.
It features 106 dB power supply rejection ratio (PSRR), 80 dB common-mode rejection ratio (CMRR), and 10⁹ Ω differential input resistance - making it suitable for high-impedance sensor interfaces where supply noise and common-mode interference must be minimized in single-supply 3 V or 5 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent amplifiers in one IC - reduces board space vs discrete op-amps and simplifies multi-channel signal conditioning. |
| Supply Voltage Range | 2.7 V to 6 V - supports direct operation from single Li-ion cells (3.0–3.6 V) or regulated 3.3 V/5 V rails. |
| Supply Current per Channel | 23 µA (typ) - enables >1-year battery life in always-on wearable sensor nodes drawing <100 µA total analog front-end current. |
| Gain-Bandwidth Product | 220 kHz - sufficient for anti-aliasing filters, ECG lead amplifiers, and thermistor signal conditioning up to ~20 kHz. |
| Input Offset Voltage | 20 µV (typ), ≤1300 µV (max over temp) - ensures <1 LSB error in 16-bit ADC interfaces with 5 V full-scale range. |
| Output Drive | ±10 mA - drives 500 Ω loads directly, eliminating need for external buffers in DAC output stages or LED bias circuits. |
| Rail-to-Rail I/O | Full swing input (0 V to VDD) and output (within 250 mV of rails at 2.5 mA) - maximizes dynamic range in low-voltage systems. |
Pinout & Package
TSSOP-14 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, thin-profile surface-mount. Pin 1 marked by beveled edge or dot; thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - connects directly to ADC input or next-stage filter without level-shifting. |
| 2 | 1IN− | Inverting input of Amp A - used for precision inverting configurations or feedback networks. |
| 3 | 1IN+ | Non-inverting input of Amp A - accepts high-impedance sensor signals (e.g., pH electrode, thermocouple). |
| 4 | GND | Analog ground reference - must be star-connected to minimize noise coupling between channels. |
| 5 | 2IN+ | Non-inverting input of Amp B - isolated from Amp A inputs to prevent crosstalk in multi-sensor designs. |
| 6 | 2IN− | Inverting input of Amp B - supports differential input configurations with matched external resistors. |
| 7 | 2OUT | Amplifier B output - shares same layout constraints as Pin 1; avoid routing near digital traces. |
| 8 | VDD+ | Positive supply - requires local 100 nF ceramic decoupling capacitor placed within 2 mm of this pin. |
| 9 | 3OUT | Amplifier C output - identical electrical behavior to Pins 1 and 7; usable for third-channel signal path. |
| 10 | 3IN− | Inverting input of Amp C - no internal connection to shutdown logic (unlike TLV2453/TLV2455). |
| 11 | 3IN+ | Non-inverting input of Amp C - fully rail-to-rail compatible; supports 0 V to VDD common-mode range. |
| 12 | 4IN+ | Non-inverting input of Amp D - electrically isolated; enables independent biasing per channel. |
| 13 | 4IN− | Inverting input of Amp D - no NC pins in this variant; all 14 pins are functional. |
| 14 | 4OUT | Amplifier D output - completes quad configuration; supports simultaneous 4-channel analog processing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3 V or 5 V supply range - critical for maximizing SNR in low-voltage ADC drivers. |
| 23 µA/channel quiescent current | Reduces system-level power budget by >50% vs comparable rail-to-rail op-amps (e.g., TLV2464), extending battery runtime. |
| 220 kHz gain-bandwidth at 23 µA | Breaks traditional micropower bandwidth trade-off - supports higher-frequency sensor signals than legacy 100-kHz-class micropower amps. |
| ±10 mA output drive capability | Drives 500 Ω loads directly - eliminates external buffer stages in DAC output buffers or active filter implementations. |
| Specified from 0°C to 70°C (C-suffix) | Guarantees parametric performance across commercial temperature range - suitable for indoor medical devices and industrial HMI panels. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464CD | Higher supply current (550 µA/ch), 6.4 MHz GBW, same TSSOP-14 package and rail-to-rail I/O. | Targeted at higher-speed applications (e.g., active filters, audio preamps) where bandwidth >200 kHz is required. | Select TLV2464CD only when >20× bandwidth increase justifies 24× higher quiescent current. |
| LPV821QDGKR | Single-channel, 650 nA supply current, 7 kHz GBW, SC70-5 package - not pin-compatible. | Optimized for ultra-long-life battery applications (10+ years) where bandwidth <10 kHz suffices. | Use LPV821QDGKR for single-ended, extreme-low-power nodes; TLV2454CD remains optimal for multi-channel, sub-250-kHz precision tasks. |
Compared with TLV2464CD, TLV2454CD trades bandwidth for 24× lower power - essential for portable medical devices with strict battery life targets. Compared with LPV821QDGKR, TLV2454CD provides four channels and 31× higher bandwidth at the cost of higher current - making it the balanced choice for compact, multi-sensor data loggers.

FAQ
Does TLV2454CD include a shutdown feature?
No, TLV2454CD does not include a shutdown terminal. The TLV2454 device variant lacks shutdown functionality - unlike TLV2450, TLV2453, and TLV2455 which integrate SHDN pins. TLV2454CD draws 23 µA per channel continuously and cannot be placed into ultralow-power (16 nA) shutdown mode. This is confirmed in the Family Package Table and pinout diagrams where no SHDN pin is assigned for TLV2454 in TSSOP-14.
What is the maximum operating temperature range for TLV2454CD?
The TLV2454CD is rated for 0°C to 70°C ambient operating temperature (C-suffix grade). It is not qualified for extended industrial or automotive ranges - variants like TLV2454ID (−40°C to 125°C) or TLV2454AID (−40°C to 125°C) provide wider temperature coverage. The C-suffix designation is explicitly defined in the "Available Options" tables for TLV2454 and confirmed in the Recommended Operating Conditions section.
Which package type is used by TLV2454CD?
TLV2454CD uses the TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm lead pitch, 14-pin thin shrink small-outline package. This is unambiguously specified in the "TLV2454 and TLV2455 AVAILABLE OPTIONS" table, where TLV2454CD is listed under the "TSSOP (PW)" column, and confirmed in the "TLV245x PACKAGE PINOUTS" diagram labeled "TLV2454 D, N, OR PW PACKAGE".
Can TLV2454CD operate from a 3 V single supply?
Yes, TLV2454CD is fully specified and characterized for 3 V single-supply operation. Electrical characteristics tables explicitly list test conditions at VDD = 3 V, including supply current (23 µA/ch), input offset voltage (≤1300 µV), and output drive (±4 mA). The recommended operating conditions confirm 2.7 V to 6 V supply range, and rail-to-rail input/output functionality ensures usable dynamic range down to 3 V.
Is TLV2454CD pin-compatible with other TLV245x quad variants?
TLV2454CD is pin-compatible with TLV2455CD in the TSSOP-14 package, sharing identical pin assignments for all 14 terminals. However, TLV2454CD is not pin-compatible with TLV2452CD (SOIC-8) or TLV2453CD (TSSOP-14 with SHDN pin), as the latter integrates dedicated shutdown pins (Pins 7 and 14) that are NC or repurposed in TLV2454CD. Pin compatibility is limited to same-package variants without functional pin reassignments.
