Product details
Overview
AD9200KSTRL from Analog Devices is a monolithic 10-bit, 20 MSPS CMOS analog-to-digital converter with on-chip sample-and-hold amplifier and programmable voltage reference, operating from 2.7 V to 5.5 V supply, delivering 54.5 dB SINAD at 3.58 MHz input, and consuming 80 mW at 3 V - used in high-speed communications receivers and video digitization systems.
For engineers reviewing the AD9200KSTRL datasheet, AD9200KSTRL pinout, AD9200KSTRL application, or AD9200KSTRL equivalent, key selection considerations include its 20 MSPS sampling rate, 0.5 LSB differential nonlinearity, built-in clamp function (enabled in AD9200KST variant), 300 MHz analog input bandwidth, and compatibility with AD876-based designs requiring low-power, pin-compatible migration.
Technical Context
The AD9200KSTRL implements a multistage differential pipeline architecture enabling guaranteed no-missing-codes operation across 0°C to +70°C. Its sample-and-hold supports both single-ended and differential inputs, with configurable input spans (1 V or 2 V p-p) via MODE/REFSENSE pin strapping.
It features three-state digital outputs, out-of-range (OTR) flag for overflow detection, and a programmable internal reference (1 V or 2 V) with external reference option. The CLAMP and CLAMPIN pins enable DC restoration for AC-coupled video signals - a function confirmed active in the AD9200KST package variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - defines quantization step size and dynamic range for baseband signal digitization |
| Sampling Rate | 20 MSPS - supports Nyquist-limited IF undersampling up to 135 MHz without aliasing |
| Differential Nonlinearity | ±0.5 LSB max - ensures monotonic transfer function and prevents missing codes in precision measurement |
| Power Dissipation | 80 mW at 3 V - enables portable and thermally constrained high-speed data acquisition |
| Analog Input Bandwidth | 300 MHz (–3 dB) - preserves fidelity of fast-rising video edges and wideband IF signals |
| SINAD | 54.5 dB at 3.58 MHz - meets NTSC/PAL video digitization SNR requirements |
| Clamp Function | Enabled in AD9200KST - allows DC restoration of AC-coupled video with ±20 mV clamp error |
Pinout & Package
AD9200KSTRL is housed in a 48-lead LQFP (ST-48) package with exposed thermal pad, rated for 0°C to +70°C operation. Pin assignments match the AD9200KST variant per Analog Devices' ordering guide and pin configuration diagrams.
| Pin/Terminal | Circuit Role | Design Meaning |

| CLK | Master Clock Input | Single-ended edge-triggered clock controlling all conversion cycles; min pulse width 22.5 ns |
| D0–D9 | Digital Output Data | Straight binary format, MSB = D9, LSB = D0; three-state controlled by THREE-STATE pin |
| OTR | Out-of-Range Indicator | Active-high flag signaling input overflow beyond REFTS/REFBS window |
| CLAMP / CLAMPIN | DC Restoration Control | CLAMP enables internal switch; CLAMPIN sets target DC level (0.5–2.7 V) for video signal clamping |
| REFTS / REFBS | Reference Sense Inputs | Define top/bottom of input span; shorted for differential mode; decoupled via REFTF/REFBF |
| REFSENSE / MODE | Reference & Input Mode Configuration | Pin-strapped to set internal reference (1 V/2 V) and analog input topology (top/bottom, center-span, differential) |
| VREF | Internal Reference Output | Provides 1 V or 2 V output depending on REFSENSE connection; bypassed with 1 µF + 0.1 µF capacitors |
| AVDD / DRVDD | Analog & Digital Supplies | Separate 2.7–5.5 V rails; AVDD powers analog core, DRVDD drives digital outputs |
| AVSS / DRVSS | Analog & Digital Grounds | Independent ground returns required for noise isolation between analog and digital sections |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9200JSTRL | Same 48-lead LQFP package and 0°C to +70°C rating, but lacks clamp circuitry (AD9200JST variant) | Not suitable for AC-coupled video requiring DC restoration; otherwise identical timing and interface | Select AD9200KSTRL when clamp functionality is required; AD9200JSTRL for cost-sensitive non-clamp applications |
| AD9201ASTRL | 10-bit, 25 MSPS, 100 mW; wider supply range (2.7–5.5 V); same LQFP-48 package; includes clamp | Higher sampling rate supports wider IF bandwidths; higher power suits mains-powered equipment over portable | Choose AD9201ASTRL for >20 MSPS needs; AD9200KSTRL remains optimal for 20 MSPS with lowest power and proven video clamp stability |

FAQ
What is the operating temperature range specified for AD9200KSTRL?
The AD9200KSTRL is specified for operation from 0°C to +70°C, matching the commercial temperature grade defined in the Analog Devices ordering guide for the AD9200KST part number. This range applies to all electrical specifications unless otherwise noted in the datasheet, and is validated for the 48-lead LQFP (ST-48) package configuration.
Does AD9200KSTRL include the built-in clamp function?
Yes, AD9200KSTRL includes the built-in clamp function. The datasheet explicitly states this feature is available in AD9200ARS and AD9200KST variants, and the ordering guide confirms AD9200KSTRL corresponds to the AD9200KST part. The CLAMP and CLAMPIN pins are fully functional, enabling DC restoration of AC-coupled video signals with ±20 mV typical clamp error.
What is the maximum analog input frequency supported by AD9200KSTRL?
AD9200KSTRL supports an analog input bandwidth of 300 MHz (–3 dB), enabling faithful digitization of fast transients and wideband IF signals. It also supports IF undersampling up to 135 MHz - meaning input signals at frequencies up to 135 MHz can be accurately aliased into baseband without violating Nyquist criteria for the 20 MSPS sampling rate.
Is AD9200KSTRL pin-compatible with AD876?
Yes, AD9200KSTRL is pin-compatible with AD876. The datasheet states "Pin Compatible with AD876" as a key feature and confirms this compatibility applies to the AD9200KST package. Both use the same 48-lead LQFP footprint and identical pin functions, allowing direct socket replacement in legacy AD876 designs with no PCB changes required.
What reference voltage options does AD9200KSTRL support?
AD9200KSTRL supports multiple reference configurations: internal 1 V (REFSENSE tied to VREF), internal 2 V (REFSENSE tied to AGND), external reference applied to REFTS/REFBS, or external divider between VREF/REFSENSE/AGND for voltages between 1 V and 2 V. All modes are enabled via pin strapping per Table I in the datasheet, with decoupling required on REFTF/REFBF.
