Analog Devices Inc. AD7278ARMZ-RL
- Part Number:
- AD7278ARMZ-RL
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3010694-AD7278ARMZ-RL
- Description:
- IC ADC 8BIT 3MSPS 8MSOP
- Datasheet:
- AD7278ARMZ-RL
Description
The AD7276/AD7277/AD7278 are 12-/10-/8-bit, high-speed, low-power, successive approximation analog-to-digital converters (ADCs). They operate from a single 2.35 V to 3.6 V 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 also initiated at this point. There are no pipeline delays associated with the part.
The AD7276/AD7277/AD7278 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 Voo of 2.35 V to 3.6 V
Power consumption: 12.6 mW at 3 MSPS with 3 V 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
Applications
Data acquisition systems
Process control
Medical instrumentation
Industrial automation
Test and measurement
