AD876ARS-8

Overview

The AD876ARS-8 is a CMOS, 10-bit, 20 MSPS analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features an on-chip input sample-and-hold amplifier and utilizes a multistage pipelined architecture with output error correction logic to ensure accurate performance and guarantee no missing codes across the full operating temperature range. The device operates from a single +5 V supply and dissipates 160 mW of power. It includes force and sense connections for reference inputs to minimize external voltage drops. The component is housed in a 48-lead Thin Quad Flatpack (TQFP) package.

Part Context

The AD876ARS-8 belongs to the AD876 product family, which consists of high-speed CMOS A/D converters. This specific part number denotes the 48-lead TQFP package variant. The series is designed for applications requiring moderate resolution at high sampling speeds, offering pin-compatible options such as the 8-bit AD876 variants.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the AD876AR and AD876ARS, which offer similar specifications but may differ in package type or bit-resolution options. Designers should verify that the replacement maintains the required 20 MSPS throughput and 160 mW power profile.
