The first devices in Maxim's new line of high-voltage op amps, the MAX9632/MAX9633 are designed using a proprietary high-speed complementary BiCMOS process (CB5HV). According to the company this analog process is optimized for AC dynamic performance, low noise, wide operating voltage range and low-drift signal conditioning. The MAX9632/MAX9633 target industrial data-acquisition applications that require precision signal conditioning at low frequencies.
The MAX9632 is a single op amp with an input-voltage noise density of 0.94nV/sq rt Hz, a low offset of 125µV (max), and an offset temperature coefficient of 0.5µV/°C (max). The MAX9633 is a dual op amp with an input-voltage noise density of 3nV/sq rt Hz, an offset of 200µV (max), and an offset temperature coefficient of 0.9µV/°C (max).

Both devices provide signal conditioning with THD specifications better than -136dB, enabling use in professional audio equipment and high-end test and instrumentation applications. Gain-bandwidth product (GBWP) is typically 55MHz for the MAX9632 and 27MHz for the MAX9633. This usable bandwidth, combined with a 4.5V to 36V operating voltage range and a typical current consumption of 3.9mA (MAX9632), allows the devices to be used in an array of industrial applications.
The MAX9632/MAX9633 are fully specified for operation over the -40°C to +125°C automotive temperature range. The products are available in a 3mm x 3mm lead-free, 8-pin TDFN package and an 8-pin SO package (MAX9632 only). Prices start at $3.39 for the MAX9632 and $2.39 for the MAX9633 (1000-up, FOB USA).
