Visão Geral
Description
Key features:
- 14-bit resolution with SNR of 74 dB (typical).
- Differential input with a 1 Vp-p full-scale range.
- LVDS (Low-Voltage Differential Signaling) or CMOS output options.
- 3.3 V single-supply operation.
- Internal reference and sample-and-hold circuit.
Packaged in a 32-lead LFCSP (5x5 mm), it offers compact integration. The AD9245BCPZ-20 is ideal for systems requiring high-speed, precision data conversion with minimal power consumption.
For detailed specs, refer to the datasheet.
Equivalent
- AD9245BCPZ-40 (40 MSPS variant)
- AD9246 (16-bit, 20/40/65 MSPS family)
- LTC2208 (16-bit, 130 MSPS, higher speed)
- ADS4149 (14-bit, 250 MSPS, faster but similar resolution)
- MAX19515 (14-bit, 80 MSPS, lower power)
Check datasheets for exact compatibility in your application.

Pinout
Key Functions:
- Analog Input (Pins 1, 2, 31, 32): Differential inputs (VIN+, VIN−) with a 2 Vpp full-scale range.
- Clock Input (Pin 30): LVDS/LVCMOS-compatible sampling clock.
- Digital Outputs (Pins 3–18, 21–28): 14-bit parallel CMOS/LVDS outputs (D0–D13) with data clock (DCO) and frame sync (FCO) for LVDS mode.
- Power (Pins 19, 20, 29): 1.8 V (core) and 3.3 V (I/O) supplies.
- Control Pins: Includes PDWN (power-down), OTR (out-of-range), and SENSE (full-scale adjust).
Designed for high-speed, low-power applications like communications and imaging.
Application
1. Communications: Software-defined radios, baseband processing.
2. Medical Imaging: Ultrasound, MRI systems.
3. Industrial: Data acquisition, instrumentation, motor control.
4. Defense/Aerospace: Radar, signal intelligence.
5. Test & Measurement: Oscilloscopes, spectrum analyzers.
Its low power, high dynamic range, and small footprint make it ideal for portable and high-performance systems.
