description

The TLC1550x and TLC1551 are data acquisition

analog-to-digital converters (ADCs) usinga 10-bit,

switched-capacitor, successive-approximation net-

work. Ahigh-speed, 3-state parallel port directly

interfaces to a digital signal processor (DSP) or

microprocessor (µP) system data bus. D0 through

D9 are the digital output terminals with D0 being

the least significant bit (LSB). Separate power

terminals for the analog and digital portions

minimize noise pickup in the supply leads.

Additionally, the digital power is divided into two

parts to separate the lower current logic from the

higher current bus drivers. An external clock can be

applied to CLKIN to override the internal system

clock if desired.

The TLC1550I and TLC1551I are characterized for

operation from −40°C to 85°C. The TLC1550M is

characterized over the full military range of −55°C

to 125°C.

This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields. These

circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 kV according to MIL-STD-883C,

Method 3015; however, it is advised that precautions be taken to avoid application of any voltage higher than maximum-rated

voltages to these high-impedance circuits. During storage or handling, the device leads should be shorted together or the device

should be placed in conductive foam. In a circuit, unused inputs should always be connected to an appropriated logic voltage level,

preferably either VCC or ground.
