DESCRIPTION

The TSA7887 – an alternate source for the AD7887 -

is

a

self-contained,

2-channel,

high-speed,

micropower, 12-bit analog-to-digital converter (ADC)

that operates from a single +2.7V to +5.25V power

supply. The TSA7887 is capable of a 125-ksps

throughput rate with an external 2MHz serial clock

and draws 0.85mA supply current.

The wideband input track-and-hold acquires signals

in 500ns and features a single-ended sampling

topology. Output data coding is straight binary and

the ADC is capable of converting full power signals

up to 2.5 MHz. The ADC also contains an integrated

2.5V reference or the VREF pin can be overdriven by

an external reference.

The TSA7887’s provides one or two analog inputs

each with an analog input range from 0 to VREF. In

two-channel operation, the analog input range is 0V

to VDD. Efficient circuit design ensures low power

consumption of 2mW (typical) for normal operation

and 3

μW in power-down operation.

The TSA7887 is fully specified from -40ºC to +125ºC

and is available in 8-pin SOIC and MSOP packages.
