The AD7810 is a high speed, low power, 10-bit A/D converter that operates from a single 2.7 V to 5.5 V supply. The part contains a 2 µs successive approximation A/D converter, with inherent track/hold functionality, a pseudo differential input and a high speed serial interface that interfaces to most microcontrollers. The AD7810 is fully specified over a temperature range of -40°C to +105°C.

By using a technique that samples the state of the CONVST (convert start) signal at the end of a conversion, the AD7810 may be used in an automatic power-down mode. When used in this mode, the AD7810 automatically powers down at the end of a conversion and "wakes up" at the start of a new conversion. This feature significantly reduces the power consumption of the part at lower throughput rates. The AD7810 can also operate in a high speed mode where the part is not powered down between conversions. In this high speed mode of operation, the conversion time of the AD7810 is 2 µs. The maximum throughput rate is dependent on the speed of the serial interface of the microcontroller.

The part is available in a small 8-pin, 0.3" wide, plastic dual-in-line package (mini-DIP); in an 8-lead, small outline IC (SOIC); and in an 8-lead microSOIC package.

PRODUCT HIGHLIGHTS

  1. Complete, 10-Bit ADC in 8-Lead Package
    The AD7810 is a 10-bit 2.3 µs ADC with inherent track/hold functionality and a high speed serial interface—all in an 8-lead microSOIC package. VREF may be connected to VDD to eliminate the need for an external reference. The result is a high speed, low power, space saving ADC solution.
  2. Low Power, Single Supply Operation
    The AD7810 operates from a single 2.7 V to 5.5 V supply and typically consumes only 9 mW of power while converting. The power dissipation can be significantly reduced at lower throughput rates by using the automatic power-down mode, e.g., at a throughput rate of 10 kSPS the power consumption is only 270 µW.
  3. Automatic Power-Down
    The automatic power-down mode, whereby the AD7810 powers down at the end of a conversion and “wakes up” before the next conversion, means the AD7810 is ideal for battery powered applications. See Power vs. Throughput Rate section.
  4. Serial Interface
    An easy to use, fast serial interface allows connection to most popular microprocessors with no external circuitry.

APPLICATIONS

  • Low Power, Hand-Held Portable Applications that Require Analog-to-Digital Conversion with 10-Bit Accuracy; e.g., Battery Powered Test Equipment, Battery-Powered Communications Systems
