Data Sheet

FEATURES

GENERAL DESCRIPTION

High performance, current input, data acquisition µModule

that includes a TIA, analog filter, ADC driver, and ADC

3 selectable T_Zsettings: 2 kΩ, 20 kΩ, and 200 kΩ

Internal 1.8 V LDO for the ADC

All passive components including supply decoupling

Small form factor: 12.00 mm × 6.00 mm CSP_BGA

Operation from a single 3.3 V supply

Full-scale input current to 800 µA (T_Z= 2 kΩ)

Fast input overload recovery

High analog input current to 40 mA

Analog filter for noise reduction and antialias filtering

Selectable 1.0 MHz and 100 MHz LPF bandwidth

Low input referred current noise: 16 pA rms

T_Z= 200 kΩ, 65,536 averages, 1 MHz analog filter

Supports input pulse widths down to 10 ns

14-bit ADC with sample rate up to 125 MSPS

Serial LVDS data output

The ADA4355 is a complete, high performance, current input

µModule®. For space savings, the ADA4355 includes all the

required active and passive components to realize a complete

current to bits data acquisition solution, supporting a small

form factor, optical modules as well as multichannel systems.

The high speed transimpedance amplifier (TIA) of the device

supports 10 ns pulse widths, allowing high spatial resolution for

Time of Flight (ToF) measurements. Additionally, the ADA4355

includes three TIA gain (T_Z) settings to maximize dynamic range.

An internal, selectable, analog low-pass filter (LPF) can limit

the device bandwidth with a corner frequency of 100 MHz to

minimize broadband noise while also serving as an antialiasing

filter for the 125 MSPS ADC. For lower bandwidth signals, or

wider signal pulses (for example, 20 µs or wider), the filter can

be set to a corner frequency of 1.0 MHz to provide additional

noise reduction.

SPI control interface

The 14-bit ADC converts the amplified voltage signal at a rate of

up to 125 MSPS and outputs the digitized signals through two

serial, low voltage differential signaling (LVDS) data lanes,

operating at rates of up to 1 Gbps per lane. The data clock

output (DCO) operates at frequencies of up to 500 MHz and

supports double data rate (DDR) operation.

Quiescent power: 546 mW, LDO enabled

Temperature range: −40°C to +85°C

The ADA4355 exhibits fast overdrive recovery from a large

input current signal and is available in a 12.00 mm × 6.00 mm

CSP_BGA package with a −40°C to +85°C operating temperature

range.
