HI3026JCQ

Analog To Digital Converters (ADC) Overview

The HI3026JCQ is an 8-bit, 120 MSPS flash analog-to-digital converter (ADC) manufactured by Renesas Electronics Corporation. It operates within a temperature range of -20°C to 75°C and utilizes a 48-lead MQFP surface-mount package. The device features a full-power analog input bandwidth of 150MHz and low power consumption of 760mW. Key electrical specifications include differential and integral linearity errors of ±0.5 LSB, with an internal 1/2 frequency divider circuit for demultiplexed output modes. It supports ECL, PECL, and TTL digital input levels and requires only a single +5V supply.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as the HI3026 series may be obsolete or discontinued. Confirm that the specific ordering suffix JCQ corresponds to the -20°C to 75°C temperature range and the 48-lead MQFP package. Ensure compatibility with existing system designs referencing direct replacements like the Sony CXA3026Q if applicable.

Analog To Digital Converters (ADC) Selection Notes

Select the HI3026JCQ for applications requiring high dynamic performance at 120 MSPS with low power dissipation. Choose DMUX mode to reduce external interface speed requirements while maintaining full conversion rates. Ensure the design accommodates the required reference voltages (VRT and VRB) and bypass capacitors for optimal linearity and noise performance.

Analog To Digital Converters (ADC) Part Context

The HI3026JCQ belongs to the HI3026 family of high-speed flash ADCs fabricated using an advanced Bipolar process. It serves as a direct replacement for the Sony CXA3026Q.
