Overview
The AD9200KST is a monolithic, single-supply, 10-bit analog-to-digital converter featuring a 20 MSPS sampling rate and an on-chip sample-and-hold amplifier. It utilizes a multistage differential pipeline architecture to guarantee no missing codes across the operating temperature range. The device operates within a supply voltage range of 2.7 V to 5.5 V, consuming 80 mW at 3 V. It includes a built-in clamp function for DC restoration in AC-coupled applications and supports both single-ended and differential input configurations.
Feature Summary
- Features a built-in clamp circuit specifically designed for DC restoration of video or AC-coupled signals.
- Supports flexible analog input configurations, allowing operation in either single-ended or differential modes.
- Includes an out-of-range indicator (OTR) to signal overflow conditions relative to the input span.
Applications
- Video signal processing requiring DC restoration capabilities
- AC-coupled communication systems
- Imaging systems with multiplexed channels
Procurement Notes
Verify that the specific ordering suffix KST corresponds to the 48-lead LQFP package option when sourcing components. Confirm the commercial temperature range specification aligns with system requirements. Ensure ESD precautions are strictly followed during handling due to the sensitivity of the CMOS structure.
Selection Notes
Select this model when a 48-lead LQFP package is required instead of the standard SSOP form factor. The KST variant provides identical electrical performance to other AD9200 models but offers different physical footprint dimensions. Consider the internal clamp feature if the application involves AC-coupled inputs needing DC level restoration without external circuitry.
Part Context
The AD9200KST belongs to the AD9200 family of high-speed, low-power CMOS ADCs. It shares pin compatibility with the legacy AD876, facilitating migration to lower supply voltages. This component is part of Analog Devices' portfolio of pipeline converters designed for portable and battery-operated applications requiring moderate resolution and speed.
Replacement Considerations
The AD9200ARS serves as a direct functional replacement offering industrial temperature range (-40°C to +85°C). The AD9200JST provides equivalent performance in the same 48-lead LQFP package but is limited to the commercial temperature range (0°C to +70°C).
