PRODUCT OVERVIEW

The ADC-207 is the industry’s first 7-bit flash

converter using an advanced high-speed VLSI

1.2 micron CMOS process. This process offers

some very distinctive advantages over other

processes, making the ADC-207 unique. The

smaller geometrics of the process achieve high

speed, better linearity and superior temperature

performance.

has very low power consumption (250mW). The

device draws power from a single +5V supply and

is conservatively rated for 20MHz operation. The

ADC-207 allows using sampling apertures as small

as 12ns, making it more closely approach an ideal

G Q

auto-balanced on every conversion to cancel out

any offsets due to temperature and/or dynamic

effects. The resistor ladder has a midpoint tap for

use with an external voltage source to improve

integral linearity beyond 7 bits. The ADC-207 also

provides the user with 3-state outputs for easy

interfacing to other components.

covering three operating temperature ranges: 0 to

+70°C, –40 to +100°C, and –55 to +125°C. Two

high-reliability “QL” models are also available.
