Large Quantities, Price Negotiable!

The AD9253TCPZ-125EP is a high-performance, quad-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices. It supports sampling rates up to 125 MSPS (million samples per second) and is designed for communication systems requiring high dynamic range, low power, and a compact package. Featuring a pipelined architecture, it integrates differential inputs and an LVDS (low-voltage differential signaling) interface, making it suitable for multi-channel data acquisition and high-speed signal processing.

Core Features:
1. Resolution and Sampling Rate: 14-bit resolution, supporting a configurable sampling rate of 125 MSPS.
2. Input Characteristics: Differential inputs, maximum input voltage 1V, and built-in sample-and-hold circuitry.
3. Interface and Power Consumption: LVDS digital outputs, 1.8V power supply, typical power consumption 110mW per channel, and SPI interface compatibility.

4. Dynamic Performance: Signal-to-Noise Ratio (SNR) of 74dB and Spurious-Free Dynamic Range (SFDR) of 90dBc ensure high-precision signal conversion.
5. Packaging and Reliability: 48-pin LFCSP package (7mm × 7mm × 0.75mm), operating temperature range of -40°C to +85°C (extended temperature support available on select batches), and RoHS compliance.

Application Scenarios:
1. Wireless communication base stations (4G/5G RF front-ends)
2. Medical imaging equipment (ultrasound, CT)
3. Industrial test and measurement instruments
4. Radar and satellite communication systems
5. Multi-channel data acquisition cards
