LTC1643HCGN

LTC1643HCGN is an Analog Devices (Linear Technology) high-speed analog-to-digital converter (ADC). It converts an analog input into a digital word for processing by microprocessors, DSPs, or FPGAs. The HCGN suffix denotes the specific package and temperature grade (packaging and operating range) used for this part.
Key points:
- Function: ADC with track-and-hold and a digital interface (SPI-compatible-style) for easy microcontroller or data-path integration.
- Resolution and speed: designed for high resolution and fast sampling (typical LTC1643-family performance spans around 12–14 bits at multi-MSPS rates, though exact figures depend on the exact member and configuration).
- Power and supply: single-supply operation with options for low power modes; suitable for instrumentation and data-acquisition systems.
- Packaging: HCGN specifies the exact physical package and industrial/temperature rating, useful for board layout and thermal planning.
Typical applications:
- Data acquisition, instrumentation, sensor interfacing, communications front-ends.
If you need exact specs (bit depth, sample rate, voltage ranges, and pinout), consult the LTC1643HCGN datasheet.

Here are the typical features of the LTC1643HCGN (high-level summary):
