AD670 is a complete 8-bit signal conditioning analog-to-digital converter, including features such as an instrumentation amplifier and a precision voltage reference. It offers high conversion speed, flexible input stage, and convenient input ranges.
The AD670 is a complete 8-bit signal conditioning analog-to-digital converter designed to interface directly with an 8-bit data bus without requiring external components or user trims. It integrates an instrumentation amplifier front end, a DAC, a comparator, a successive approximation register (SAR), a precision voltage reference, and a three-state output buffer on a single monolithic chip.
The device operates on a single +5 V supply and provides differential inputs with excellent common-mode rejection, allowing direct interface to various transducers. It supports two input ranges (0 mV to 255 mV and 0 to 2.55 V) and can be configured for both unipolar and bipolar inputs. The AD670 is available in four package types and five grades, with specifications guaranteed over the operating temperature range.
No external components or user trims are required to interface with full accuracy.
The conversion time of the device is 10 µs.
Yes, the AD670 will operate on the +5 V system supply.
It supports two input ranges: 0 mV to 255 mV and 0 to 2.55 V.
