Product details
Overview
TLV2254IDR from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, micropower operation. It delivers 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 34 µA per channel supply current across a 2.7 V to 8 V supply range. It supports single- or split-supply configurations and is widely used in battery-powered sensor signal conditioning and ADC interface circuits.
For engineers reviewing the TLV2254IDR datasheet, TLV2254IDR pinout, TLV2254IDR application, or TLV2254IDR equivalent, key selection criteria include rail-to-rail output swing, ultra-low input bias current for high-impedance sources, sub-35 µA per-channel quiescent current, guaranteed 850 µV max input offset voltage (A-grade), and compatibility with 3 V and 5 V systems in industrial and portable equipment.
Technical Context
The TLV2254IDR employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input impedance and low noise. Its input stage operates with common-mode voltage extending to the negative rail, enabling true single-supply operation without level-shifting circuitry.
Each of the four amplifiers features independent internal biasing and is fully characterized over −40°C to +125°C. The device exhibits 63° phase margin and 15 dB gain margin at unity gain with 50 kΩ load and 100 pF capacitive load, ensuring stable operation in precision closed-loop configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2254AIDR | Guaranteed 850 µV max input offset voltage (vs. 1500 µV max for TLV2254IDR) | Better DC accuracy for precision measurement; identical noise, power, and bandwidth | Select TLV2254AIDR when system-level offset budget requires <0.5 mV total error at room temperature |
| MCP6004T-I/ST | Higher 100 µA/channel supply current; 17 nV/√Hz noise; rail-to-rail I/O; 1.8–6.0 V supply | Wider supply range but higher power; not qualified for automotive temp range | Choose MCP6004T-I/ST only for cost-sensitive consumer designs where 125°C operation is unnecessary |

FAQ
What is the maximum operating temperature range for TLV2254IDR?
The TLV2254IDR is rated for operation from −40°C to +125°C, meeting industrial and automotive under-hood requirements. This specification is verified per the manufacturer's recommended operating conditions table and applies across the full 2.7 V to 8 V supply range. Thermal derating follows the D-package dissipation rating of 5.8 mW/°C above 25°C ambient.
Does TLV2254IDR support true single-supply operation with input signals at ground potential?
Yes, TLV2254IDR supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD−), allowing inputs down to 0 V when powered from a single positive supply. This eliminates the need for external bias networks in sensor interfaces, as confirmed in the VICR specification (0 V to VDD+ −1.3 V at 3 V supply).
How does the noise performance of TLV2254IDR compare to earlier TI micropower op-amps?
TLV2254IDR delivers 19 nV/√Hz input voltage noise at 1 kHz-four times lower than competitive micropower solutions cited in the datasheet, such as the TLC27L4 (≈75 nV/√Hz). This improvement stems from optimized Advanced LinCMOS™ input stage design and is measured under identical test conditions (VDD = 3 V, TA = 25°C).
Can TLV2254IDR drive ADC inputs directly without external buffering?
Yes, TLV2254IDR's rail-to-rail output swing and low 220 Ω closed-loop output impedance (at 25 kHz) enable direct driving of SAR and delta-sigma ADC inputs. Its output can settle within 1 µs to 0.1% for 1 V step under 100 pF load, satisfying timing requirements for 1 MSPS converters without added buffers.
Is TLV2254IDR pin-compatible with the TLV2324 or other legacy TI quad op-amps?
No, TLV2254IDR is not pin-compatible with TLV2324. While both are 14-pin SOIC quad op-amps, TLV2254IDR uses standard channel ordering (Ch1–Ch2–Ch3–Ch4), whereas TLV2324 has different pin assignments for inverting/non-inverting inputs and outputs. PCB layout must be verified against the TLV2254IDR-specific pin diagram in Figure 3 of SLOS185D.
