- **Sampling Rate:** Up to 65Msps (Mega samples per second)  
- **Input Voltage Range:** 1.5Vpp (peak-to-peak)  
- **Power Supply:** +3.3V  
- **Power Consumption:** 310mW (typical at 65Msps)  
- **DNL (Differential Non-Linearity):** ±0.5 LSB (max)  
- **INL (Integral Non-Linearity):** ±1.0 LSB (max)  
- **SNR (Signal-to-Noise Ratio):** 68dB (typical at 30MHz input)  
- **SFDR (Spurious-Free Dynamic Range):** 80dB (typical at 30MHz input)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 48-pin TQFP (Thin Quad Flat Pack)  

### **Descriptions:**
The MAX1257BETM+ is a high-performance ADC designed for applications requiring high-speed data conversion with low power consumption. It features an internal track-and-hold (T/H) circuit and a pipelined architecture, ensuring accurate signal acquisition at high sampling rates. The device is suitable for communications, medical imaging, and test equipment applications.

### **Features:**
- **High-Speed Conversion:** Up to 65Msps  
- **Low Power Operation:** 310mW at full speed  
- **Wide Input Bandwidth:** 300MHz (full-power)  
- **Internal Reference:** On-chip 1.25V bandgap reference  
- **Differential Inputs:** Supports differential or single-ended operation  
- **LVDS-Compatible Outputs:** Low-voltage differential signaling for noise immunity  
- **Power-Down Mode:** Reduces power consumption when inactive  
- **Evaluation Kit Available:** Simplifies design integration  

The MAX1257BETM+ is RoHS-compliant and designed for high-performance signal processing in demanding environments.
