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

Product Features

• 10-bit, 1.25 MSPS
• Glueless serial interface
• 3-V or 5-V operation
• Low power
• 8 mW at 3 V
• 25 mW at 5 V
• Auto-powerdown: 10 µA max
• Characterized for operation from 0°C to 70°C

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 µA 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 the ideal choice for compact, low power, or remote high-speed systems. The TLV1572 easily adds flexibility to system design while saving board space as well as reducing board pin-count, design time and system cost.

The TLV1572 is available in an 8-pin SOIC package.
