New Item: 1WAD_5V and 1WAD_20mA

1 WAD_5V and 1 WAD_20mA  are our new item. They are both 1 wire Quad A/D converter.

Here is the feature:

Different:

1W20mA  is a 20mA current sense converter,itsinternal is 250Ω resistors with 1% precision, it can change current 0-20mA into 0-5V voltage.

Same:

(1) Four high-impedance inputs to measure analog voltages over the 1-Wire® bus

(2) User programmable input range (2.56V, 5.12V), resolution (1 to 16 bits) and alarm thresholds

(3) 5V, single supply operation

(4) Very low power: 2.5 mW active, 25 μW idle

(5) Built-in multidrop controller allows multiple DS2450’s to be identified and operated on a common 1-Wire bus

(6) Responds to Conditional Search if the analog voltage crosses the alarm thresholds

(7) Channels not used as analog input can serve as open drain digital outputs for closed-loop control Directly connects to a single port pin of a microprocessor and communicates at up to 16.3k bits per second

(8)Directly connects to a single port pin of a microprocessor and communicates at up to 16.3k bits per second

(9) Overdrive mode boosts communication speed to 142k bits per second

(10) On-chip 16-bit CRC-generator for safeguarding data transfers Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48- bit serial number 8-bit   CRC tester) assures absolute traceability because no two parts are alike 8-bit family code specifies device communication requirements to bus master Operating temperature range from -40°C to +85°C

(11)  Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48- bit serial number 8-bit   CRC tester) assures absolute traceability because no two parts are alike 8-bit family code specifies device communication requirements to bus master Operating temperature range from -40°C to +85°C  

(12) 8-bit family code specifies device communication requirements to bus master.

(13) Operating temperature range from -40°C to +85°C.

(14) Compact, low cost 8-pin SOIC surface mount package

(15) Keep working without the external power
