Hot-selling and scarce AD7895ANZ-3 5 V 12-Bit Serial 3.8 ms ADC DIP8 spot stock

Product Descriptions

The AD7895 is a fast 12-bit ADC that operates from a single+5 V supply and is housed in a small 8-pin mini-DIP and 8-pinSOIC . The part contains a 3.8 µs successive approximation A/Dconverter, an on-chip track/hold amplifier, an on-chip clock anda high speed serial interface .

Output data from the AD7895 is provided via a high speed,serial interface port . This two-wire serial interface has a serialclock input and a serial data output with the external serial clockaccessing the serial data from the part .

In addition to the traditional dc accuracy specifications such aslinearity and full-scale and offset errors, the AD7895 is specifiedfor dynamic performance parameters, including harmonicdistortion and signal-to-noise ratio .

The part accepts an analog input range of ±10 V (AD7895-10),±2.5 V (AD7895-3), 0 V to 2.5 V (AD7895-2) and operatesfrom a single +5 V supply, consuming only 20 mW max .

The AD7895 features a high sampling rate mode and, for lowpower applications, a proprietary automatic power-down modewhere the part automatically goes into power down onceconversion is complete and“wakes up” before the next conversion cycle .

The part is available in a small, 8-pin, 0.3" wide, plastic dual-inline package (mini-DIP) and in an 8-pin, small outline IC (SOIC).
