Why Choose TLV2373 Over Alternatives?
The TLV2373 provides a unique blend of low power, rail-to-rail performance, and wide voltage support. Unlike typical op-amps that may sacrifice bandwidth or output swing, this device maintains full-range signal capability even at lower supply voltages, which is critical for battery-operated and low-headroom analog designs. Its high input impedance and low offset ensure accurate signal processing across a range of environmental conditions.
Key Features & Functional Advantages
