The converter operates off a single +2.7 V to +5.5 V supply and contains a 2.3 µs successive approximation A/D converter, track/hold circuitry, on-chip clock oscillator and 8-bit wide parallel interface. The parallel interface is designed to allow easy interfacing to microprocessors and DSPs. The 10-bit conversion result is read by carrying out two 8-bit read opera- tions. The first read operation accesses the 8 MSBs of the ADC conversion result and the second read accesses the 2 LSBs. Using only address decoding logic the AD7813 is easily mapped into the microprocessor address space. When used in its power-down mode, the AD7813 automatically powers down at the end of a conversion and powers up at the start of a new conversion. This feature significantly reduces the power consumption of the part at lower throughput rates. The AD7813 can also operate in a high speed mode where the part is not powered down between conversions. In this mode of opera- tion the part is capable of providing 400 kSPS throughput. The part is available in a small, 16-lead, 0.3" wide, plastic dual- in-line package (DIP), in a 16-lead, 0.15" wide, narrow body small outline IC (SOIC) and in a 16-lead thin shrink small outline package (TSSOP). PRODUCT HIGHLIGHTS 1. Low Power, Single Supply Operation The AD7813 operates from a single +2.7 V to +5.5 V sup- ply and typically consumes only 10.5 mW of power. The power dissipation can be significantly reduced at lower throughput rates by using the automatic power-down mode. 2. Automatic Power-Down The automatic power-down mode, whereby the AD7813 goes into power-down mode at the end of a conversion and powers up before the next conversion, means the AD7813 is ideal for battery powered applications; e.g., 34.6 µW @ 1 kSPS. (See Power vs. Throughput Rate section.) 3. Parallel Interface An easy to use 8-bit-wide parallel interface allows interfacing to most popular microprocessors and DSPs with minimal external circuitry. 4. Dynamic Specifications for DSP Users In addition to the traditional ADC specifications, the AD7813 is specified for ac parameters, including signal-to-noise ratio and distortion. |
