MAX350 General Description

The MAX349/MAX350 are 8-channel and dual 4-channel serially controlled multiplexers (muxes). These muxes conduct equally well in either direction. On-resistance (100½ max) is matched between switches to 16½ max and is flat (10½ max) over the specified signal range.

These CMOS devices can operate continuously with dual power supplies ranging from ±2.7V to ±8V or a single supply between +2.7V and +16V. Each mux can handle rail-to-rail analog signals. The off-leakage current is only 0.1nA at +25°C or 5nA at +85°C.

Upon power-up, all switches are off and the internal shift registers are reset to zero.

The serial interface is compatible with SPI™/QSPI™ and MICROWIRE™. Functioning as a shift register, it allows data (at DIN) to be clocked in synchronously with the rising edge of clock (SCLK). The shift register's output (DOUT) enables several MAX349s or MAX350s to be daisy chained.

All digital inputs have 0.8V or 2.4V logic thresholds, ensuring both TTL and CMOS-logic compatibility when using ±5V supplies or a single +5V supply.

MAX3503 General Description

The MAX3503/MAX3505 evaluation kits (EV kits) simplify evaluation of the MAX3503 and MAX3505 CATV upstream amplifiers. The kits include a data interface that can be programmed through the parallel port of a standard PC.Software (Windows 95/98® compatible) is available at www.maxim-ic.com/TechSupport/other.htm to facilitate this function. This software allows programming of all available features through a simple user interface.

Access to the device input and output is provided through 50 SMA connectors. The input is terminated with 50. The output circuit includes a 75 to 50 minimum-loss pad for use with 50 equipment.

MAX3503 Features

· Single-Supply Operation
· Output Level Range Up to 64dBmV (MAX3505)
· Gain Programmable in 0.5dB Steps
· Transmit-Disable Mode
· Shutdown Mode
· Control Software Available for Download
· Fully Assembled and Tested Surface-Mount Board
