Product details
Overview
AD9283BRSZ-80 from Analog Devices is an 8-bit, 80 MSPS monolithic analog-to-digital converter with on-chip track-and-hold, internal 1.25 V reference, and single 3.0 V supply operation. It delivers 46.5 dB SNR at 41 MHz input frequency, supports 1 Vp-p analog input range, and features TTL/CMOS-compatible digital outputs powered by a separate VDD pin for 2.5 V/3.3 V logic interfacing - used in handheld scopemeters and low-cost digital oscilloscopes.
For engineers reviewing the AD9283BRSZ-80 datasheet, AD9283BRSZ-80 pinout, AD9283BRSZ-80 application, or AD9283BRSZ-80 equivalent, key selection considerations include its 80 MSPS sampling rate, 475 MHz analog bandwidth, power-down mode (4.2 mW), differential or single-ended input flexibility, and SSOP-20 package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The AD9283BRSZ-80 implements a bit-per-stage pipeline ADC architecture with switch-capacitor techniques: five stages resolve the 5 MSBs and drive a flash converter for the 3 LSBs. Error correction and output staging align data with four-pipeline latency and ensure no missing codes across the full industrial temperature range.
Its ENCODE input is TTL/CMOS-compatible with 1.5 V threshold and 4.3 ns minimum pulsewidth high; aperture uncertainty is 5 ps rms. The analog input circuit includes internal biasing at 0.3 × VD, 10 kΩ input resistance, and 2 pF capacitance - optimized for stable performance up to 475 MHz full-power bandwidth.
Key Specifications

FAQ
What is the maximum sampling rate supported by the AD9283BRSZ-80?
The AD9283BRSZ-80 supports a maximum conversion rate of 80 MSPS, as confirmed in the "Switching Performance" section of the datasheet. At this rate, it maintains guaranteed SNR of 46.5 dB at 41 MHz input frequency and full 8-bit resolution with no missing codes across the industrial temperature range. Operation above 80 MSPS is not characterized or supported for this variant.
Does the AD9283BRSZ-80 require an external voltage reference?
No, the AD9283BRSZ-80 includes an on-chip 1.25 V reference (VREF OUT) that can be used directly by connecting Pin 2 (VREF OUT) to Pin 3 (VREF IN). This eliminates the need for an external reference in most applications. If higher precision or adjustable full-scale range is required, an external reference may be applied to Pin 3 - but the internal reference must still be bypassed with 0.1 µF to ground per the datasheet.
How does the power-down mode function on the AD9283BRSZ-80?
The AD9283BRSZ-80 enters power-down mode when a logic HIGH is applied to Pin 1 (PWRDWN). Within two clock cycles, total power dissipation drops to 4.2 mW and all digital outputs (D7–D0) transition to high-impedance state. Recovery to full performance takes approximately 15 clock cycles after PWRDWN returns LOW, ensuring minimal latency when resuming acquisition.
What package type and footprint does the AD9283BRSZ-80 use?
The AD9283BRSZ-80 uses a 20-lead shrink small outline package (SSOP, RS-20) with 0.65 mm lead pitch and exposed pad-less construction. Its outline dimensions are 7.50 mm × 5.38 mm × 1.78 mm (L × W × H), and it is compatible with standard SSOP reflow profiles. The datasheet provides full mechanical drawings and recommended PCB land patterns.
Can the AD9283BRSZ-80 accept single-ended analog inputs?
Yes, the AD9283BRSZ-80 supports both differential and single-ended analog input configurations. For single-ended use, one input (e.g., AIN) is driven with the signal while the complementary input (AIN) is terminated to ground via a 0.1 µF capacitor and 25 Ω series resistor - as specified in the "Analog Input" section of the datasheet to maintain input matching and optimize dynamic performance.
