High Precision Operational Amplifiers

The op amps (short for operational amplifiers) have broad applications. For sensing small signals, low offset voltage and low noise are required. Our first IC, AT8551, is such a product. It has very low maximum offset voltage, <5µV (competition AD8551: 10µV); low noise, <0.75µV_P-P @0.01Hz to 10Hz (competition AD8551: 1µV_P-P @0Hz to 10Hz); high slew rate, 2.7V/µs (competition AD8551: 0.4µV/µs); high speed, 4.5MHz (competition AD8551: 1.5MHz); and, the best of all, low cost, $0.78 @1000pcs (competition AD8551: $1.25 @1000pcs).

Step-Down DC-DC Converters

A Step-down DC-DC converter can also be called buck converter, buck regulator, or DC-DC step-down switching regulator. From its name, we can tell that it converts a power supply source to a lower voltage output at high power efficiency, often > 90%.

Analog Technologies offers the following types of step-down DC-DC converter ICs: ATDC1934, ATDC2934, ATI2202, ATI2301 and ATI2305.

ATI2202EV1 is an evaluation board for ATI2202.
