ADC0808S250HW-C18

Analog To Digital Converters (ADC) Overview

The ADC0808S250HW-C18 is a single-channel, high-speed, 8-bit Analog-to-Digital Converter (ADC) designed for telecommunication and tape drive applications. It supports sampling frequencies up to 250 MHz with an analog input bandwidth of 560 MHz. The device features differential analog inputs and selectable clock inputs compatible with either 1.8 V CMOS or Low-Voltage Differential Signals (LVDS). Digital outputs operate at 1.8 V CMOS levels, supporting both binary and 2's complement coding formats. It includes an integrated voltage regulator for the input common-mode reference and operates within an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• High-speed sampling rate up to 250 MHz with only 2 clock cycles latency
• Selectable 1.8 V CMOS or LVDS clock input modes
• Programmable Complete Conversion Signal (CCS) for flexible acquisition control
• Integrated voltage regulator for input common-mode reference

Analog To Digital Converters (ADC) Applications

• 2.5G and 3G cellular base infrastructure radio transceivers
• Wireless access systems and Wireless Local Area Network (WLAN) infrastructure
• Fixed telecommunications and optical networking
• Tape drive applications

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix C18 corresponds to the specific package variant listed in official documentation. Confirm the manufacturer source, as the datasheet identifies Integrated Device Technology (IDT) as the original producer. Ensure compatibility with Renesas Electronics Corporation if IDT assets have been acquired. Check for updated revision history regarding the HTQFP48 package thermal characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a sampling rate of 250 MHz is required. Choose between the 125 MHz version (ADC0808S125) if lower power consumption is prioritized over maximum speed. Ensure the system design accommodates the 1.8 V digital supply voltage (VCCD/VCCO) and 3.3 V analog supply voltage (VCCA). Verify that the differential input signal amplitude fits within the 2.0 V peak-to-peak range defined by the internal reference settings.

Analog To Digital Converters (ADC) Part Context

The ADC0808S series comprises two variants: the ADC0808S125 operating at 125 MHz and the ADC0808S250 operating at 250 MHz. Both share identical pinouts, functional descriptions, and package types (HTQFP48). The primary distinction lies in the maximum clock frequency specification. This component belongs to a family of high-speed, low-resolution ADCs optimized for wideband signal acquisition.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC0808S125HW-C18 is a direct functional substitute within the same package, differing only in the maximum sampling frequency limit. No other cross-model replacements are documented in the provided datasheet.
