This converter is completely self-contained with a

stable, low noise, internal zener voltage reference;

high speed current switches; a resistor ladder net-

work; and a fast settling, low noise output operational

amplifier all on a single monolithic chip. The

converters are operated using two power supplies that

can range from ±5V to ±12V. Power dissipation with

±5V supplies is typically less than 200mW. Also

included is a provision for external adjustment of the

MSB error (differential linearity error at bipolar zero)

to further improve total harmonic distortion (THD)

specifications if desired. Few external components

are necessary for operation, and all critical

specifications are 100% tested. This helps assure the

user of high system reliability and outstanding overall

system performance.

The PCM56 is packaged in a high-quality 16-pin

molded plastic DIP package or SOIC and has passed

operating life tests under simultaneous high-pressure,

high-temperature, and high-humidity conditions.

DESCRIPTION

The PCM56 is a state-of-the-art, fully monotonic,

digital-to-analog converter that is designed and

specified for digital audio applications. This device

employs ultra-stable nichrome (NiCr) thin-film

resistors to provide monotonicity, low distortion, and

low differential linearity error (especially around

bipolar zero) over long periods of time and over the

full operating temperature.

combined drift error due to gain, offset, and linearity over temperature. (4) Measured with an active clamp to provide a low impedance for approximately 200ns. (5) All

specifications assume +V
