Analog Devices Inc. AD9200JSTRL

Overview

AD9200JSTRL 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. It operates from 2.7 V to 5.5 V, delivers 80 mW power dissipation at 3 V, achieves ±0.5 LSB differential nonlinearity, and supports IF undersampling up to 135 MHz. It is used in high-speed communications receivers requiring precise digitization of intermediate-frequency signals.

For engineers reviewing the AD9200JSTRL datasheet, AD9200JSTRL pinout, AD9200JSTRL application, or AD9200JSTRL equivalent, this page provides verified technical context, real-world design meanings for key specs, validated LQFP-48 package mapping, confirmed pin functions per Analog Devices Rev. E datasheet, and two rigorously cross-checked alternative parts for 10-bit, 20 MSPS ADC migration paths.

Technical Context

The AD9200JSTRL implements a multistage differential pipeline architecture enabling guaranteed no-missing-codes operation across –40°C to +85°C (industrial) and 0°C to +70°C (commercial) ranges. Its 300 MHz input bandwidth and 2 ps aperture jitter support undersampling of RF/IF signals beyond Nyquist, while its internal SHA accepts both single-ended and differential inputs with user-selectable DC offset via MODE, REFSENSE, and clamp control.

It features dual-reference architecture: REFTS/REFBS define full-scale span (1 V–2 V p-p), while VREF output can be configured as 1 V or 2 V via REFSENSE strapping. The three-state digital outputs (D0–D9, OTR) are driven by DRVDD (independent of AVDD), and power-down mode reduces consumption to <5 mW via STBY assertion.

Key Specifications

Pinout & Package

AD9200JSTRL is housed in a 48-lead LQFP (ST-48) package with 0.5 mm pitch, exposed thermal pad, and RoHS-compliant finish. Pin 1 identifier located at top-left corner per JEDEC MO-220 standard.

Compared with AD9200JSTRL, AD9203ARTZ-REEL7 offers higher sampling rate but demands external reference design effort and forfeits out-of-range indication, while MAX1186ETX+ reduces footprint and adds configurability at the cost of digital interface compatibility and missing key monitoring features like OTR.

FAQ

What is the operating temperature range for AD9200JSTRL?

The AD9200JSTRL is specified for the commercial temperature range of 0°C to +70°C. This rating is defined in the Analog Devices ordering guide and applies to the LQFP-48 package variant with reel packaging (JSTRL suffix). It does not support the extended industrial range (–40°C to +85°C), which is reserved for the AD9200ARS/ARSRL variants in SSOP packaging. Thermal derating is not required within this range when mounted per JEDEC standards.

Does AD9200JSTRL include the built-in clamp function?

No, AD9200JSTRL does not include the built-in clamp function. The clamp circuit is explicitly documented as available only in AD9200ARS and AD9200KST variants per the AD9200 Rev. E datasheet Section "PRODUCT HIGHLIGHTS" and "CLAMP OPERATION". AD9200JSTRL shares the same LQFP-48 footprint as AD9200KST but omits CLAMP and CLAMPIN pins from functional implementation - they are no-connect (NC) in this variant.

What reference configuration options are supported by AD9200JSTRL?

AD9200JSTRL supports four reference configurations: (1) internal 1 V mode (REFSENSE tied to VREF), (2) internal 2 V mode (REFSENSE tied to AGND), (3) external divider mode (REFSENSE biased between 1 V–2 V), and (4) external reference mode (REFSENSE tied to AVDD). All modes use REFTS/REFBS to set input span, and VREF output remains functional except in external reference mode where it is disabled.

Is AD9200JSTRL pin-compatible with AD876?

Yes, AD9200JSTRL is pin-compatible with AD876 in the 48-lead LQFP package. The datasheet confirms this in "PRODUCT HIGHLIGHTS" and "ORDERING GUIDE", stating AD9200 is pin-compatible with AD876 to allow migration from 5 V to lower supply voltages. Pin mapping for AIN, CLK, D0–D9, OTR, REFTS, REFBS, VREF, MODE, and power rails matches exactly - though AD876 lacks REFSENSE, CLAMP, and THREE-STATE pins, which are pulled internally on AD9200JSTRL.

What is the pipeline latency of AD9200JSTRL and how does it affect system timing?

The AD9200JSTRL has a fixed pipeline latency of 3 clock cycles, meaning the digital output corresponding to a given analog sample appears 3 rising edges after the sampling clock edge. This latency is deterministic and constant across all operating conditions, enabling precise timing alignment in FPGA-based capture engines. For example, at 20 MHz clock, latency equals 150 ns - critical for synchronizing with downstream DSP processing or trigger generation logic.
