The AD7813 is a high-speed, microprocessor-compatible, 8-/10-bit analog-to-digital converter with a maximum through- put of 400 kSPS.
The AD7813 is a high‑speed, microprocessor‑compatible analog‑to‑digital converter offering 8‑/10‑bit resolution and a maximum throughput of 400 kSPS. It operates from a single 2.7 V to 5.5 V supply and includes on‑chip track‑and‑hold, a clock oscillator, and an 8‑bit wide parallel interface.
Key features include low power consumption (10.5 mW normal operation, 34.6 µW at 1 kSPS in automatic power‑down), a conversion time of 2.3 µs, and availability in DIP, SOIC and TSSOP packages. The device provides a 0 V to VDD analog input range and a 1.2 V to VDD reference input.
| Supply Voltage Range | 2.7 V to 5.5 V |
|---|---|
| Resolution | 10 bits |
| Conversion Time | 2.3 µs max |
| Power Consumption (Normal Operation) | 10.5 mW at VDD = 3 V |
The AD7813 can operate at up to 400 kSPS.
It consumes about 10.5 mW when VDD = 3 V.
The conversion time is specified as 2.3 µs maximum.
