ADC08351CILQ/NOPB

Analog To Digital Converters (ADC) Overview

The ADC08351CILQ/NOPB is an 8-bit, 42 MSPS analog-to-digital converter fabricated on a 0.35 micron CMOS process. It operates from a single +3V supply and consumes 40 mW typically in active mode, reducing to less than 7 mW in power-down mode. The device features an internal sample-and-hold function and TRI-STATE outputs. Key performance metrics include a typical Effective Number of Bits (ENOB) of 7.2 bits at a 4.4 MHz input frequency with a 42 MHz clock, and a full-power bandwidth of 120 MHz. It is designed for industrial temperature ranges from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• High-speed conversion with a maximum sampling rate of 42 MSPS and 120 MHz full-power bandwidth.
• Low power consumption of 40 mW typically, with a dedicated power-down mode consuming under 7 mW.
• Internal sample-and-hold circuitry and self-biasing inputs allowing optional AC coupling.
• TRI-STATE digital outputs compatible with CMOS and TTL logic levels.

• Digital still cameras and camcorders
• CCD imaging applications
• Medical imaging equipment
• Set-top boxes and personal computer video

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the required design constraints, as the NOPB suffix indicates a specific manufacturing variant of the LLP package. Confirm that the single +3V supply requirement aligns with the system's power architecture. Ensure the industrial temperature range (-40°C to +85°C) meets the operational environment specifications. Check for any specific ordering suffix requirements regarding tape and reel quantities if applicable to the production volume.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed 8-bit resolution is required with minimal external support circuitry. The internal reference and biasing simplify designs compared to converters requiring external drivers. Consider the 4 pF to 11 pF dynamic input capacitance when selecting driving amplifiers. Ensure the clock source has low jitter to maintain the specified SNR and SFDR performance, particularly at higher input frequencies.

Analog To Digital Converters (ADC) Part Context

The ADC08351 series was originally developed by National Semiconductor before Texas Instruments acquired the company. The part number ADC08351CILQ/NOPB represents the LLP (Leadless Chip Package) version of this high-speed ADC. The NOPB suffix denotes a lead-free and RoHS-compliant manufacturing variant. This device belongs to a family of low-cost, low-power video ADCs designed for portable and battery-operated applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADC08351CIMTC (TSSOP package). For different package requirements, verify electrical compatibility with other 8-bit, 42 MSPS SAR ADCs from Texas Instruments or Analog Devices, ensuring similar supply voltage and interface characteristics.
