The temperature range for the J, K, and L versions is from 0°C to +70°C; for the A, B, and C versions is−40°C to +85°C; and for the T version is −55°C to +125°C.
V
SNR calculation includes distortion and noise components.
Measured with respect to internal reference and includes bipolar offset error.
Sample tested @ +25°C to ensure compliance.
Conversion time specification for the AD7870A device with internal clock used is 8 μs/10 μs minimum/maximum.
