Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX3532 is a programmable power amplifier for use in upstream cable applications. The device outputs up to 62dBmV (continuous wave) through a 1:2 (voltage ratio) transformer when driven with 36dBmV at its input. MAX3532 features variable gain, which is controlled via a 3-wire digital serial bus and available in 1dB steps. The operating frequency ranges from 5MHz to 42MHz.

The MAX3532 offers three operating modes: high power, low noise, and transmit disable. High-power mode achieves the highest output levels, while low-noise mode achieves the lowest output noise when driving lower output levels. Transmit disable mode places the MAX3532 in a high-isolation state with minimum output noise, for use between bursts in TDMA systems.

Two power-down modes of MAX3532 are also available. Software shutdown mode permits power-down of all analog circuitry while maintaining the programmed gain setting. Shutdown mode of MAX3532 disables all circuitry and reduces current consumption below 10µA.

The MAX3532 comes in a 36-pin SSOP package screened for the extended-industrial temperature range (-40°C to +85°C).
