Fastest low-power, 10-bit, 1.25-MSPS serial ADC

The TLV1572 is the industry’s first high-speed 10-bit ADC to gluelessly interface with TMS320 DSPs or (Q)SPI digital microcontrollers, while packaged in a tiny 8-pin SOIC.

This device accepts an analog input range from 0 V to VCC and digitizes the input at a maximum 1.25-MSPS throughput rate. Power dissipation is only 8 mW with a 3-V supply or 25 mW with a 5-V supply.

The TLV1572 features a 10 ľA auto-power down mode which reduces power consumption whenever the conversion is not performed. Implemented with a successive approximation architecture, the TLV1572 has a typical Differential Non-Linearity (DNL) of ± 0.3 LSB and a typical Integral Non-Linearity (INL) of ± 0.5 LSB. The Signal-to-Noise Ratio + Distortion is 59 dB (typ).

The small 8-pin SOIC package, combined with an extremely high sample rate-to-power ratio, makes this ADC well suited for compact, low-power, or remote high-speed systems. The TLV1572 adds flexibility to system design while saving board space, and reducing board pin-count, design time and system cost.
