The AD7891ASZ-1 is an integrated circuit (IC) component that belongs to the AD7891 family of analog-to-digital converters (ADCs) manufactured by Analog Devices. This ADC is designed specifically for applications where high accuracy and low power consumption are crucial. Here is an overview of the AD7891ASZ-1 and its key features.
The AD7891ASZ-1 is a 12-bit, high-speed, successive approximation ADC with a maximum sampling rate of 1 MSPS (Mega Samples Per Second). It operates with a single power supply ranging from 2.35V to 5.25V, making it suitable for low power and portable applications. The ADC also features a low power shutdown mode, allowing further reduction of power consumption when not in use.
One of the key features of the AD7891ASZ-1 is its excellent linearity, ensuring accurate conversion of analog signals. It exhibits a maximum integral nonlinearity (INL) of ±0.5 LSBs (Least Significant Bits) and a maximum differential nonlinearity (DNL) of ±1 LSB, guaranteeing precise and reliable data conversion.
Moreover, the AD7891ASZ-1 incorporates an onboard track-and-hold (T/H) function, which enables simultaneous sampling and conversion of the input signal, improving the overall efficiency of the system
