Analog Devices AD670 8-Bit Signal Conditioning ADC Datasheet
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.

How long does a conversion take?
The conversion time of the AD670 is 10 µs.
How are input ranges selected?
Input ranges are selected by internal scaling resistors and the BPO/UPO pin, providing low‑range (0‑255 mV) and high‑range (0‑2.55 V) options for both unipolar and bipolar configurations.
