Overview
The AD9058ATD/883B is a dual-channel, 8-bit analog-to-digital converter (ADC) operating at up to 50 MSPS. It integrates two independent ADCs on a single monolithic IC with an optional on-board voltage reference. The device features low input capacitance of 10 pF and consumes less than 1 W of power. It supports flexible input ranges including unipolar positive operation from 0 V to 2 V using the internal 2 V reference or bipolar inputs via external references. Digital I/O is TTL compatible. The component is housed in a hermetic 48-lead side-brazed ceramic dual in-line package (CDIP-48) and is qualified for military temperature ranges from –55 °C to +125 °C.
Feature Summary
- Integrates two matched 8-bit ADCs on a single chip utilizing a patented interpolating architecture that reduces circuit complexity and die size compared to traditional flash converters.
- Includes an on-board band gap voltage reference capable of driving both ADC channels simultaneously for simplified system design.
- Features low input capacitance of 10 pF and low power consumption of less than 1 W while maintaining high dynamic performance.
- Provides flexible analog input range options, supporting unipolar positive operation (0 V to 2 V) or bipolar configurations via external references.
Applications
- Quadrature demodulation for communications systems requiring digitization of in-phase (I) and quadrature (Q) components.
- Digital oscilloscopes and time-domain measurement equipment.
- Electronic warfare systems.
- Radar signal processing applications.
Procurement Notes
Verify the specific suffix ATD/883B indicates military qualification and hermetic packaging. Confirm availability status as the datasheet marks the AD9058 series as obsolete. Ensure procurement sources provide valid traceability documentation for the 883B specification level.
Selection Notes
Select this component when a dual-channel, high-speed ADC solution is required within a single package footprint. The internal voltage reference simplifies board layout by reducing external component count. Verify that the TTL-compatible digital outputs align with the logic family used in the target system interface.
Part Context
The AD9058ATD/883B belongs to the AD9058 family of dual 8-bit ADCs manufactured by Analog Devices. It shares architectural similarities with other high-speed data converters but is distinct in its integrated dual-channel design and interpolating architecture. The /883B suffix denotes compliance with MIL-PRF-38534 specifications for enhanced reliability.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. The datasheet explicitly lists the AD9058 series as obsolete. Designers should consult current Analog Devices product portfolios for modern replacements.
