ADS8380IBRHPRG4

Analog To Digital Converters (ADC) Overview

The ADS8380IBRHPRG4 is an 18-bit, 600-kHz sampling analog-to-digital converter (ADC) featuring a pseudo-differential input and a high-speed serial interface. It integrates a 4.096-V internal reference with an onboard buffer. The device operates with a single +5-V analog supply (+VA) and a digital supply (+VBD) ranging from 2.7 V to 5.25 V. Key performance metrics include ±2 LSB typical integral nonlinearity (INL), 91 dB SINAD at 1 kHz, and 119 dB SFDR. Power consumption is 115 mW at full throughput, dropping to 15 mW in Nap mode and 10 μW in power-down.

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix 'RHPRG4' corresponds to the tape-and-reel packaging containing 1000 units per reel. Confirm the 'I' grade designation for the industrial temperature range of -40°C to 85°C. Ensure the component is RoHS compliant and lead-free as indicated by the G4 suffix. Cross-reference the specific ordering information table to validate availability and package dimensions against current manufacturer documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 18-bit precision and 600-kHz sampling speed are required. The integrated reference simplifies design by reducing external component count. Choose the IB variant over the I variant if stricter linearity specifications (±4 LSB max INL vs ±6 LSB) are necessary. Ensure the system supports the required digital supply voltage range of 2.7 V to 5.25 V for the logic interface.

Analog To Digital Converters (ADC) Part Context
