| The [[adi>AD4003]]/[[adi>AD4007]]/[[adi>AD4011]]/[[adi>AD4020]] are low noise, low power, high speed, 18-bit, precision successive approximation register (SAR) analog-to-digital converters (ADCs). The [[adi>AD4003]], [[adi>AD4007]], and [[adi>AD4011]] offer 2 MSPS, 1 MSPS, and 500 kSPS throughputs, respectively. They incorporate ease of use features that reduce signal chain power consumption, reduce signal chain complexity, and enable higher channel density. The high-Z mode, coupled with a long acquisition phase, eliminates the need for a dedicated high power, high speed ADC driver, thus broadening the range of low power precision amplifiers that can drive these ADCs directly while still achieving optimum performance. The input span compression feature enables the ADC driver amplifier and the ADC to operate off common supply rails without the need for a negative supply while preserving the full ADC code range. The low serial peripheral interface (SPI) clock rate requirement reduces the digital input/output power consumption, broadens processor options, and simplifies the task of sending data across digital isolation. | The [[adi>AD4003]]/[[adi>AD4007]]/[[adi>AD4011]]/[[adi>AD4020]] are low noise, low power, high speed, 18-bit, precision successive approximation register (SAR) analog-to-digital converters (ADCs).

| The [[adi>ADAQ4003]] is an 18/20-bit precision data acquisition sub-system SiP design on a laminate that includes the [[adi>AD4003]] ADC with a fully differential driver the ADA4945, a reference buffer (the ADA4807), a precision resistor iPassive network on a separate die along with discrete capacitors and resistors. The device solves many design challenges for a wide range of applications similar to AD400x, yet it still provides the flexibility. It offers over 75% area savings compared to discrete design (i.e. Increased channel density and reduced signal chain BOM) and reduces TTM. | The [[adi>ADAQ4003]] is an 18-bit precision data acquisition sub-system SiP design on a laminate that includes the [[adi>AD4003]] ADC with a fully differential driver the ADA4945, a reference buffer (the ADA4807), a precision resistor iPassive network on a separate die along with discrete capacitors and resistors.
