ADC3662IRSBT

Analog To Digital Converters (ADC) Overview

The ADC3662IRSBT is a dual-channel, 16-bit analog-to-digital converter (ADC) from the Texas Instruments ADC366x family. It operates at a fixed sampling rate of 25 MSPS with a noise spectral density of -154 dBFS/Hz and an input bandwidth of 900 MHz (-3 dB). The device features a serial LVDS (SLVDS) interface supporting 2-wire, 1-wire, and 1/2-wire configurations. Power consumption is typically 117 mW per channel at 25 MSPS using an external reference. It includes on-chip digital filters for decimation by 2, 4, 8, 16, or 32, and offers a latency as low as one clock cycle in 1-wire mode. The component is housed in a 40-pin WQFN package measuring 5 mm x 5 mm and supports an industrial temperature range from -40°C to +105°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix IRSBT corresponds to the specified industrial temperature grade and tape-and-reel packaging configuration. Confirm that the specific revision level matches the design requirements, as documentation updates may affect pin descriptions or electrical characteristics. Ensure compatibility with the required voltage reference and power supply specifications during the procurement phase.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3662 when a fixed 25 MSPS sampling rate is required between the slower ADC3661 and faster ADC3663 models. Consider the internal or external reference options based on system noise sensitivity. Evaluate the SLVDS interface lane configuration against the downstream receiver capabilities to optimize board routing and power consumption.

Analog To Digital Converters (ADC) Part Context

The ADC3662 belongs to the ADC366x series, which includes the ADC3661 (10 MSPS), ADC3663 (65 MSPS), and ADC3664 (14-bit, 125 MSPS). These devices share a common 40-pin WQFN footprint and are pin-to-pin compatible within their respective speed grades. This family is designed for applications requiring low noise and high dynamic range in a compact form factor.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3661 and ADC3663 are direct pin-compatible replacements offering different sampling rates. For higher throughput requirements, the ADC3664 provides 14-bit resolution at 125 MSPS but differs in bit depth.
