AiT Semiconductor has introduced a groundbreaking advancement in operational amplifier technology with the launch of the AO1378 amplifier. This cutting-edge amplifier heralds a new era of zero-drift, micro-power CMOS operational amplifiers, significantly enhancing performance in a wide range of low-power precision applications.
Boasting a bandwidth of 1.8 MHz, the AO1378 amplifier stands out with its rail-to-rail inputs and outputs, coupled with single-supply operation ranging from 1.8 V to 5.5 V. This unique combination of attributes empowers the AO1378 to deliver optimal results, particularly in scenarios where low-power precision is paramount.
One of AO1378's key innovations is the utilization of chopper-stabilized techniques, resulting in a remarkably low offset voltage of less than 5 μV (maximum) and near-zero drift across varying temperatures. This design breakthrough, combined with a low quiescent supply current of 180 μA per amplifier and an exceptionally low input bias current of 20 pA, makes the AO1378 an ideal solution for applications demanding low offset, minimal power consumption, and high impedance.
In addition, the AO1378 boasts an exceptional Common-Mode Rejection Ratio (CMRR) without the crossover issues typically associated with traditional complementary input stages. This feature translates to superior performance when driving analog-to-digital converters (ADCs), maintaining differential linearity without compromise.
The AO1378's adaptability is further underscored by its availability in SOT-25 and SOP8 packages, catering to a variety of design requirements.
