• Manufacturer Part Number: AD362
• Description: PrecisionSample-and-Hold with 16-Channel Multiplexer
• Manufacturer: AD [Analog Devices]

Interfacing to Special Purpose ADCs
The ADS200 series of ADCs perform a 12-bit conversion in SO
microseconds and feature totally adjustment-free operation,
high accuracy, and a small hermetically-sealed 24-pin package.
These ADCs are often used in high-reliability applications
and, like the AD362SD (which operates over the -SSoC to
+12SoC temperature range) are available processed to MIL-
STD-883, Class B. The ADS200 series meets all of the inter-
facing requirements for direct connection to the AD362 as
shown in Figure 8a. System throughput rate is typically 16kHz.
