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-pin SOIC. The part contains a 3.8 µs successive approximation A/D converter, an on-chip track/hold amplifier, an on-chip clock and a 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 serial clock input and a serial data output with the external serial clock accessing the serial data from the part. In addition to the traditional dc accuracy specifications such as linearity and full-scale and offset errors, the AD7895 is specified for dynamic performance parameters, including harmonic distortion 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 operates from a single +5 V supply, consuming only 20 mW max. The AD7895 features a high sampling rate mode and, for low power applications, a proprietary automatic power-down mode where the part automatically goes into power down once conversion is complete and "wakes up" before the next conversion cycle. The part is available in a small, 8-pin, 0.3" wide, plastic dual-in-line package (mini-DIP) and in an 8-pin, small outline IC (SOIC). PRODUCT HIGHLIGHTS * Fast, 12-Bit ADC in 8-Pin Package The AD7895 contains a 3.8 µs ADC, a track/hold amplifier, control logic and a high speed serial interface, all in an 8-pin package. This offers considerable space saving over alternative solutions. * Low Power, Single Supply Operation The AD7895 operates from a single +5 V supply and consumes only 20 mW. The automatic power-down mode, where the part goes into power-down once conversion is complete and “wakes up” before the next conversion cycle, makes the AD7895 ideal for battery-powered or portable applications. * High Speed Serial Interface The part provides high speed serial data and serial clock lines allowing for an easy, two-wire serial interface arrangement. * Fast 12-Bit ADC with 3.8 µs Conversion Time * 8-Pin Mini-DlP and SOIC * Single 5 V Supply Operation * High Speed, Easy-to-Use, Serial Interface * On-Chip Track/Hold Amplifier * High Input Impedance https://elecena.pl/product/17761960/true-bipolar-input-5-v-single-supply-12-bit-serial-3-8-s-adc-in-8-pin-package 2021-04-17 https://elecena.pl/product/17761960/true-bipolar-input-5-v-single-supply-12-bit-serial-3-8-s-adc-in-8-pin-package 2025-01-17
