Overview
The AD1860R-J is a 16-bit, single-channel digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It utilizes BICMOS technology and accepts serial input data formats. The device operates on a single +5 V supply with a -5 V negative supply rail. Key electrical specifications include a signal-to-noise ratio of 110 dB and a fast settling time of 1.5 microseconds, which supports high oversampling rates. The component is housed in a 16-pin plastic dual in-line package (PDIP-16) with a 2.54 mm pin spacing. It functions as a two's complement DAC and includes optional trim capabilities for super-linear performance.
Feature Summary
- 110 dB Signal-to-Noise Ratio (SNR)
- 1.5 µs Settling Time
- 16-Bit Resolution with Serial Input
- +5 V / -5 V Dual Supply Operation
Applications
- High-End Compact Disc Players
- Digital Audio Amplifiers
- DAT Recorders and Players
- Synthesizers and Keyboards
Procurement Notes
Verify the specific suffix 'R-J' against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with existing serial interface timing requirements. Confirm RoHS compliance status for the specific manufacturing lot. Check for active production status or obsolescence notices. Validate that the PDIP-16 package fits the target PCB footprint.
Selection Notes
Select this component when a 16-bit audio DAC with low noise and fast settling is required. The 110 dB SNR makes it suitable for high-fidelity audio applications. The serial interface simplifies connection to microcontrollers or DSPs. Consider the 1.5 µs settling time if high oversampling ratios are needed for noise shaping. Verify power supply constraints match the +5V/-5V requirement.
Part Context
The AD1860 series belongs to a family of 16-bit PCM audio DACs from Analog Devices. It is pin-compatible with the AD1856 and AD1860 models, facilitating design upgrades or replacements within existing audio circuits. The device is designed specifically for professional and high-end consumer audio equipment requiring precise digital-to-analog conversion.
Replacement Considerations
The AD1856 and AD1860 are documented as pin-compatible alternatives. Verify functional equivalence regarding serial protocol and trim requirements before substitution.
