AD7276, AD7277, AD7278, AD7274, AD7273
The AD7276, AD7277, AD7278, AD7274, AD7273 are 12-bit/10-bit/8-bit, high speed, low power, successive approximation analog-to-digital converters (ADCs), respectively. The parts operate from a single 2.35V to 3.6V power supply and feature throughput rates of up to 3 MSPS. The parts contain a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 55 MHz.
The conversion process and data acquisition are controlled using CS and the serial clock, allowing the devices to interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS, and the conversion is initiated at this point. There are no pipeline delays associated with the part.
The AD7276, AD7277, AD7278, AD7274, AD7273 use advanced design techniques to achieve very low power dissipation at high throughput rates.
The reference for the part is taken internally from VDD. This allows the widest dynamic input range to the ADC; therefore, the analog input range for the part is 0 to VDD. The conversion rate is determined by the SCLK.
Features
- Throughput rate: 3 MSPS
- Specified for VDD of 2.35V to 3.6V
- Power consumption 12.6 mW at 3 MSPS with 3V supplies
- Wide input bandwidth 70 dB SNR at 1 MHz input frequency
- Flexible power/serial clock speed management
- No pipeline delays
- High speed serial interface SPI-/QSPI™-/MICROWIRE-/DSP compatible
- Temperature range: −40°C to +125°C
- Power-down mode: 0.1 μA typical
- 6-lead TSOT package
- 8-lead MSOP package
- AD7476 and AD7476A pin compatible
PRODUCT HIGHLIGHTS
1. 3 MSPS ADCs in a 6-lead TSOT package.
2. AD7476/AD7477/AD7478 and AD7476A/AD7477A/AD7478A pin compatible.
3. High throughput with low power consumption.
4. Flexible power/serial clock speed management. This allows maximum power efficiency at low throughput rates.
5. Reference derived from the power supply.
6. No pipeline delay. The parts feature a standard successive approximation ADC with accurate control of the sampling instant via a CS input and once-off conversion control.
