ADC0808S250HW/C1,1

Analog To Digital Converters (ADC) Overview

The ADC0808S250HW/C1,1 is a differential, high-speed, 8-bit Analog-to-Digital Converter (ADC) optimized for telecommunication transmission control systems and tape drive applications. It supports signal sampling frequencies up to 250 MHz with a maximum analog input frequency of 560 MHz. The device features selectable 1.8 V CMOS or LVDS clock inputs and provides 1.8 V CMOS compatible static digital inputs and outputs. It offers binary or 2's complement output coding, only 2 clock cycles latency, and an integrated voltage regulator for the input common-mode reference. The component operates within an industrial temperature range from -40 °C to +85 °C and is supplied in an HTQFP48 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix C1,1 against the manufacturer's current documentation to confirm packaging details and compliance status. Ensure that the HTQFP48 package dimensions align with the target PCB footprint design. Confirm the required supply voltages: 3.3 V for analog supply (VCCA) and 1.8 V for digital supplies (VCCD, VCCO). Check for any updated revision history or errata sheets associated with this part number before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC0808S250HW/C1,1 when a sampling rate up to 250 MHz is required. Choose between 1.8 V CMOS or LVDS clock inputs based on the system's clock driver capabilities; LVDS requires an external resistor between 80 Ω and 120 Ω. Configure the output coding (binary or 2's complement) using the OTC pin. Adjust the full-scale input range via the FSIN/REFSEL pin, utilizing either the internal reference circuit or an external reference voltage between 1.15 V and 1.35 V.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC0808S family, which includes the ADC0808S125 variant supporting up to 125 MHz sampling. Both variants share identical architectural features, including the HTQFP48 package and interface options. The '250' designation specifically indicates the higher speed capability of this model compared to the 125 MHz version.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC0808S125HW/C1,1 is a confirmed substitute within the same family, offering identical functionality with a reduced maximum sampling frequency of 125 MHz.
