True Bipolar Input, 5 V Single Supply, 14-Bit, Serial 4.5 µs ADC in 8-Pin Package
In addition to the traditional dc accuracy specifications such as linearity, full-scale and offset errors, the AD7894 is also specified for dynamic performance parameters including harmonic distortion and signal-to-noise ratio. The part accepts an analog input range of ±10 V (AD7894-10), ±2.5V (AD7894-3), 0 V to 2.5 V (AD7894-2), and operates from a single +5 V supply consuming only 20 mW typical.
The AD7894 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 outline IC (SOIC).
