Overview

Alternate Source for AD7887 Single-supply Operation: to +5.25V INL: - TSA7887A One or Two Single-ended Analog Inputs Internal Wide-bandwidth Track-and-Hold Internal +2.5-V Reference Flexible Power/Throughput-Rate Management at 125ksps (Internal VREF ON) at 125ksps (Internal VREF OFF) Shutdown-mode Supply Current: 1A (max) SPI�/QSPITM/MICROWIRETM/DSP-Compatible 1 Serial Interfaces Operating Temperature Range: +125�C 8-pin SOIC and MSOP Packaging The � an alternate source for the is a self-contained, 2-channel, high-speed, micropower, 12-bit analog-to-digital converter (ADC) that operates from a single to +5.25V power supply. The TSA7887 is capable 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 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 0V to VDD. Efficient circuit design ensures low power consumption of 2mW (typical) for normal operation and 3W in power-down operation. The TSA7887 is fully specified from to +125�C and is available in 8-pin SOIC and MSOP packages.

Guaranteed no missing codes to 11 bits (A Grade) VDD = 5V, dual-channel mode VDD = 3V, dual-channel mode Single-channel mode Dual-channel mode Single-channel mode, external reference Single-channel mode, internal reference
