The TLV278x single supply operational amplifiers provide rail-to-rail input and output capability. The TLV278x takes the minimum operating supply voltage down to 1.8 V over the extended industrial temperature range (–40°C to 125°C) while adding the rail-to-rail output swing feature. The TLV278x also provides 8 MHz bandwidth from only 650 µA of supply current. The maximum recommended supply voltage is 3.6 V, which allows the devices to be operated from (±1.8 V supplies down to ±0.9 V) two rechargable cells.

The combination of wide bandwidth, low noise, and low distortion makes it ideal for high speed and high resolution data converter applications.

All members are available in PDIP, SOIC, and the newer, smaller SOT-23 (singles), MSOP (duals), and TSSOP (quads).

CIRCUIT060074 — High-side current sensing with comparator circuit

This high-side, current sensing solution uses one comparator with a rail-to-rail input common mode range to create an over-current alert (OC-Alert) signal at the comparator output (COMP OUT) if the load current rises above 1 A. The OC-Alert signal in this implementation is active low. So when the (...)
