Driver for 14-Bit, 4.5Msps ADC Operates Over a Wide
Gain Range

Introduction
The LTC В®2314-14 is a 14-bit, 4.5Msps, serial output
ADC with an integrated high performance reference.
The single-ended input of the LTC2314-14 is easy
to drive and in many instances does not require a
buffer. A driver, such as the LT6236 op amp, may be
required for a signal that is small or has high output
impedance. The LT6236 is a 215MHz gain bandwidth
product, rail-to-rail output op amp/SAR ADC driver that
features 1.1nV/в€љHz input-referred noise voltage density
and draws only 3.5mA of supply current with a typical
offset of only 100ВµV. The LT6236 is a good choice for
these applications because of its high bandwidth, low
noise, low supply current and low offset. ten depending on the value of R3, as shown in Table 1.
Capacitor C1 and resistor R1 limit the input bandwidth
to 68MHz. C1 also acts as a charge reservoir for the
ADC sample-and-hold capacitor and helps to isolate the
LT6236 from the transient that occurs at AIN when the
ADC goes into sample mode. R1 is also used to help …
