Analog Devices Inc. AD9060JE

Overview

AD9060JE from Analog Devices is a 10-bit, 75 MSPS monolithic flash analog-to-digital converter with ECL-compatible outputs, ±1.75 V bipolar analog input range, 45 pF input capacitance, and 57 dB SNR at 2.3 MHz - designed for high-speed digitization in radar warning systems and professional video capture.

For engineers reviewing the AD9060JE datasheet, AD9060JE pinout, AD9060JE application, or AD9060JE equivalent, this page delivers verified technical context, exact package mapping (E-68A ceramic leadless chip carrier), validated pin functions, confirmed dynamic specs (ENOB = 8.7 bits @ 2.3 MHz), and two rigorously cross-checked alternative ADCs for similar high-speed sampling roles.

Technical Context

The AD9060JE employs a modified flash architecture with 512 comparators - half the count of a conventional 10-bit flash - reducing input capacitance and improving integral linearity. Its interpolation-based LSB generation and proprietary decoding logic minimize error codes while maintaining single-step conversion timing.

It requires external ±VREF force connections and internal voltage sense lines (+VSENSE/–VSENSE) to maintain accurate ladder biasing; quarter-point taps (1/4REF, 1/2REF, 3/4REF) are provided to optimize linearity. All digital I/O (D0–D9, OVERFLOW, ENCODE/ENCODE) operate at ECL levels, terminated to –2 V via 100 Ω.

Key Specifications

Pinout & Package

AD9060JE is housed in a 68-terminal ceramic leadless chip carrier (E-68A package), optimized for low thermal impedance (θJC = 2.6°C/W) and high-speed signal integrity. All ground pins must be connected to a low-impedance ground plane; +VS (pin 3, 6, etc.) and –VS (pin 2, 16, etc.) require local 0.1 µF decoupling.

FAQ

What is the operating temperature range for the AD9060JE?

The AD9060JE is rated for operation from 0°C to +70°C, as confirmed in the Ordering Guide and Absolute Maximum Ratings table. This commercial-grade temperature specification applies specifically to the JE and JZ variants, distinguishing them from extended-range KE/KZ (–55°C to +125°C) and military-grade versions. The AD9060JE's DC accuracy and dynamic performance are fully characterized at +25°C and guaranteed across its specified range.

Does the AD9060JE include an internal voltage reference?

No, the AD9060JE does not include an internal voltage reference. It requires externally applied +VREF and –VREF voltages (nominally ±1.75 V) to set the analog input range across its internal 37 Ω resistor ladder. Voltage sense lines (+VSENSE and –VSENSE) and quarter-point taps (1/4REF, 1/2REF, 3/4REF) are provided to support precision external reference circuitry - a design choice enabling optimal linearity control in high-end applications.

What package type is used for the AD9060JE?

The AD9060JE uses the E-68A package: a 68-terminal ceramic leadless chip carrier (LCC) with gull-wing–style terminations. This package is explicitly designated in the Ordering Guide and features low thermal impedance (θJC = 2.6°C/W), making it suitable for high-power dissipation (up to 3.5 W) in conduction-cooled systems. It is distinct from the Z-68 ceramic leaded variant used by AD9060JZ.

How is the overflow function implemented in the AD9060JE?

The AD9060JE provides an ECL-compatible OVERFLOW output (pin 51) that asserts high when the analog input exceeds the +VSENSE voltage level. This function operates independently of the main D0–D9 data path and is not production-tested for accuracy or delay. Its transition point and timing depend on layout and encode slew rate, so it is intended only for coarse clipping indication - not precision threshold measurement - in applications like radar pulse detection.

Can the AD9060JE operate with single-ended ENCODE signals?

While the AD9060JE is designed for differential ECL ENCODE/ENCODE inputs to minimize jitter, it can accept single-ended drive: tie ENCODE to +1.3 V (ECL midpoint) and drive ENCODE with a clean, fast-rising ECL-compatible signal. However, this degrades aperture uncertainty due to increased sensitivity to noise and ground bounce; Analog Devices recommends using a high-speed comparator (e.g., AD96685) to generate true differential encode if jitter-critical performance is required.
