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).
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
