TC35080P

The TC35080P is a kind of high precision, high speed monolithic CMOS 10-bit successive approximation A/D converter with seperate serial input and output. The device has a clock input (IOCK) which shifts serial data in (write mode) and out (read mode), a data output enable (DOE) which controls output timing and a successive approximation register status (SARS) output. These permit easy interfacing to other devices. The frequency of the built-in A/D conversion is determined by the values of an external RC network connected to the CKI and CKO terminals. For the user desires, an external clock may be connected to the CKI terminal.

There are some features of TC35080P as follows: (1)high accuracy: 1LSB typ; (2)high speed conversion: 11s @ fCKI=2.0 MHz; (3)single power supply: 5.0 V±10%; (4)serial I/O; (5)built-in 8-channel analog multiplexer; (6)latched 3-state output; (7)built-in A/D oscillator; (8)zero or full scale adjustment free. The typical applications include industrial control instruments and electrical wiring apparatus.

What comes next is about the maximum ratings of TC35080P: (1)DC supply voltage, VDD: VSS-0.5 to VSS+7 V; (2)input voltage, VIN: VSS-0.5 to VDD+0.5 V; (3)output voltage, VOUT: VSS-0.5 to VDD+0.5 V; (4)reference supply voltage, VREF: VSS-0.5 to VDD+0.5 V; (5)analog ground voltage, AGND: VSS-0.5 to VDD+0.5 V; (6)input current, IIN: ±10 mA; (7)power dissipation, PD: 300 mW; (8)storage temperature range, Tstg: -65 to 150. Then is about the recommended operating conditions (VSS=0 V): (1)supply voltage, VDD: 4.5 V min, 5.0 V typ and 5.5 V max; (2)input voltage, VIN: 0 to VDD V; (3)reference voltage, VREF: 3.0 V min, VDD V typ and VDD V max at AGND=0 V; (4)analog grand voltage, AGND: 0 V min, 0 V typ and 0 V max at VREF=5.0 V.
