General Description
The CAE1200 is an eight channel simultaneously sampled 16-bit ADC. The CAE1200 is capable of achieving a sampling rate of 200 Ksps per channel. Each Channel has a standalone analog front end including a Programmable Gain Amplifier(PGA), Low Pass Filter(LPF) and Clamp protection. CAE1200 provide flexible digital interface to interface with different controller. The CAE1200 operates form a 5V supply and can accommodate ±10V, ±5V and ±2.5Vtrue bipolar input signals. The analog input impedance of each channel is 680 KΩ allowing direct connection to the signal source in many cases. This eliminates the need for an external buffer. CAE1200 features a front-end anti-alias filter with attenuation of approximately 40dB while sampling at 200kSPS。Over-Sampling function can be turned on to improve ~3dB in SNR for each over-sampling increment.
