TC5090AP

The TC5090AP is a pentaphase integration 8-bit A/D converter of high precision and low power consumption, which is mounted in a compact 16-pin standard package. The 8-bit output data can be taken out in the form of time-shared higher order 4 bits and lower order 4 bits on four 3-state data outputs. This output system of TC5090AP is designed specifically considering interface to 4-bit CPU. The features of low power consumption and compact outline are applicable to battery-driven small-sized instruments. TC5090AP can be applicated in various control instruments (for temperature, humidity, pressure, etc.), home electric appliances, electric wiring apparatuses, battery-driven instruments.

The features of TC5090AP can be summarized as (1)high precision: ±1 LSB MAX.; (2)low power consumption: 10mW(Typ.) @(VDD=5V; fOSC=1MHz ); (3)single power supply: VDD=5±1.5V; (4)high-speed conversion: 2mS(Max.) @fOQSg=1.5MHz; (5)reference clock oscillation circuit contained (CR oscillation); (6)3-state output with output latch; (7)TTL/CMOS compatible digital input/output; (8)offset automatic correction.

The absolute maximum ratings of TC5090AP are (1)DC supply voltage VDD: VSS-0.5-VSS+8V; (2)input voltage VIE: VSS-0.5~VDD+0.5V; (3)output voltage VOUT: VSS-0.5~VDD+0.5V; (4)DC input current IIN: ±10mA; (5)power dissipation PD: 300mW; (6)operating temperature range Topr: -40~85°C; (7)storage temperature range Tstg: -65~150°C.
